That Prophet and David’s Lord

Together, these four passages raise the first tension. John 1 keeps the Christ, Elijah, and that Prophet distinct; Deuteronomy 18 promises a prophet like Moses; and Deuteronomy 34:10 then says no prophet like Moses arose again in Israel. The wording does not settle the promised prophet’s identity — it holds the question open. A prophet like Moses is promised, and yet none such arose in Israel, so the phrasing deserves to be tested carefully.

John 1 and Deuteronomy 18:18: Existing Jewish and Christian Readings

Jewish and Christian readings show how differently the same wording has been received. Jewish interpretation usually keeps Deuteronomy 18 inside Israel’s own prophetic history: it may point to Joshua, to prophets raised within Israel after Moses, or to the continuing prophetic office. Rashi — Rabbi Shlomo Yitzchaki, the eleventh-century French Jewish commentator whose Torah commentary became one of the classic Jewish interpretive references — reads the promise in relation to prophets raised for Israel from prophet to prophet.

Because John 1 is a later Christian text, Jewish interpretation does not treat its questioning of John the Baptist as a binding messianic framework. The scene remains historically useful all the same, because it preserves a Gospel-era distinction among the Christ, Elijah, and that Prophet. At the very least, it shows that expectation language around the period could be more complex than a single merged title.

Christian interpretation usually takes a different route. Through Acts 3 and Acts 7, Deuteronomy 18 is applied to Jesus, and John 1’s separate questions are harmonized in him: he is read as the Messiah, the Prophet like Moses, and the fulfillment of Israel’s expectation.

Each reading has its own internal logic within its tradition. The question is whether either arises directly from the wording itself. John 1 begins with three separate possibilities. Deuteronomy 18:18, in the direct divine formulation, does not say from among the Israelites, but from among their brothers. The traditional readings may function within Jewish and Christian theological systems, but the immediate linguistic data remains more open than those systems often allow.

John 1: A Third Expected Figure, Not a Generic Prophet

The questions put to John the Baptist are striking because they are not one question asked three ways. The priests and Levites sent from Jerusalem ask about three figures in sequence: the Christ, Elijah, and that Prophet. John denies all three identifications. The structure itself presents that Prophet as a third expected figure, not as a generic prophet and not as a simple synonym for the Messiah.

And this is the record of John, when the Jews sent priests and Levites from Jerusalem to ask him, 'Who art thou?' And he confessed, and denied not; but confessed, 'I am not the Christ.' And they asked him, 'What then? Art thou Elias?' And he saith, 'I am not.' 'Art thou that Prophet?' And he answered, 'No.'

The Greek phrase is ὁ προφήτης — literally the Prophet. Older English, the King James Version especially, captures this identifying force as that Prophet. Either way, the expression is not a prophet in general. It refers to a known expected figure. Just as importantly, it is placed after the Christ and Elijah as another question in the same series, which makes the separateness of the category visible in the syntax itself.

Deuteronomy 18:18: The Direct Divine Formulation

That distinction matters: verse 15 gives Moses’ public wording to Israel, while verse 18 gives the direct divine formulation. In verse 18 the speaker is God, and the promise is stated directly:

I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.

A word-by-word reading of Deuteronomy 18:18

At word level, the sentence turns on three linked features: the prophet’s origin, his likeness to Moses, and the form of revelation placed in his mouth:

The linguistic center is for them and from among their brothers. Since them refers to Israel as a whole, their brothers is a marked kinship expression rather than a simple repetition of Israel. It does not by itself identify an external line, but it keeps the question of Israel’s related brother-peoples open. In Israel’s biblical world, descent, tribe, house, and kinship were central categories of identity; lineage terms were not used casually.

The phrase therefore cannot simply be treated as though it were linguistically identical to from among Israel; its kinship force still requires explanation. The wording keeps a brother-people standing in kinship with Israel within the field of interpretation.

Deuteronomy 34:10: Why In Israel Matters

The question becomes sharper when Deuteronomy 18 is read beside the Torah’s own closing statement about Moses:

And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face.

The verse does not settle the identity of the promised prophet. Its force is as a control. If Deuteronomy 18 promises a prophet like Moses, and Deuteronomy 34:10 says no prophet like Moses arose again in Israel, then the promise remains larger than a casual appeal to later Israelite prophetic succession.

A Jewish institutional reading may take Deuteronomy 18 as the general line of Israelite prophets after Moses, and that reading has a long history. But Deuteronomy 34:10 makes it difficult to say that the Moses-like description was fully satisfied by an ordinary continuation of Israel’s prophetic office. The text itself sets Moses apart from the prophets who came after him in Israel.

That is what gives from among their brothers its importance: the promised prophet may stand in relation to Israel without simply arising inside Israel.

The Torah’s own brother-language is wider than Jacob alone

This reading does not rest on a modern, casual use of the word brother. It rests on the Torah’s own kinship language. Deuteronomy can call the descendants of Esau Israel’s brothers:

Ye are to pass through the coast of your brethren the children of Esau, which dwell in Seir; and they shall be afraid of you: take ye good heed unto yourselves therefore.

Edom too is treated as a brotherly kin-group because of the Esau-Jacob relationship:

Thou shalt not abhor an Edomite; for he is thy brother: thou shalt not abhor an Egyptian; because thou wast a stranger in his land.

These examples show that the Torah can use brother-language for a related people outside Jacob’s descendants. On linguistic grounds, therefore, their brothers cannot be sealed in advance inside Jacob’s line alone. It keeps a related Abrahamic brother-line in serious view.

Here Ishmael re-enters the question. He is not outside Abraham’s house: Genesis presents him as Abraham’s son outside Jacob’s line. Within the Torah’s own narrative world, the reader reaches Deuteronomy 18 after Ishmael has already been blessed with twelve princes and a great nation. The phrase from among their brothers therefore does not fall into an empty field.

A later Gospel saying echoes the same possibility of transfer: the kingdom is taken from its present holders and given to a nation bringing forth its fruits, not vaguely to nations in general. This does not name Ishmael by itself, but it strengthens the Abrahamic weight of the brother-line reading.

Why the Ishmaelite Line Matters

The Ishmaelite line matters because the later prophetic claim associated with Prophet Muhammad is presented within the Abrahamic family. Within Islamic tradition and Arab genealogical memory, Prophet Muhammad is placed in the line of Ishmael, Abraham’s son outside Jacob’s line. Within the framework opened by Deuteronomy 18:18, that makes the Ishmaelite line not a random option, but the major Abrahamic brother-line outside Jacob’s descendants.

The Torah gives Ishmael a distinct nation-forming promise:

And as for Ishmael, I have heard thee: Behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.

The geographical pattern points in the same direction. Genesis places Ishmael in the wilderness of Paran:

And he dwelt in the wilderness of Paran: and his mother took him a wife out of the land of Egypt.

Deuteronomy 33:2 then gives a striking sacred-geographical sequence:

The LORD came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them.

Sinai evokes Moses. Seir is associated with Edom, another brother-people related to Israel through Esau. Paran, in the Torah’s own narrative world, is connected with Ishmael. The sequence reinforces the Abrahamic horizon opened by Deuteronomy 18:18.

The Ishmaelite reading therefore rests on a convergence of three elements: the kinship phrase their brothers, the Abrahamic status of Ishmael, and the Paran horizon connected with Ishmael’s dwelling. Since Prophet Muhammad is the major prophetic figure historically claimed from the Ishmaelite-Arabian line, the question of Ishmael’s lineage becomes central to the interpretation of that Prophet.

Deuteronomy 18 and John 16: The Same Received-Speech Profile

Deuteronomy 18:18 describes both the prophet’s origin and the form of his revelation: I will put My words in his mouth, and he shall speak unto them all that I shall command him. The emphasis reaches beyond wisdom, inspiration, or spiritual insight. The divine words are placed in his mouth, and he speaks what God commands.

John 16:13 uses a closely related action-profile for the coming figure: he does not speak from himself, but speaks what he hears.

Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.

Read together, Deuteronomy 18:18 and John 16:13 form a shared definition of received speech. In Deuteronomy, God says, I will put My words in his mouth. In John, the coming figure shall not speak of himself, but whatsoever he shall hear, that shall he speak. The common pattern is not independent teaching, private speculation, or general inspiration; it is transmitted revelation — words given or heard from God and then delivered to others.

Christian interpretation identifies the Johannine figure with the Holy Spirit, while Acts applies Deuteronomy 18 to Jesus. That reading is treated separately below. At the level of wording, however, Deuteronomy 18 and John 16 preserve a strikingly similar profile: a coming figure associated with guidance, who does not speak from himself, but delivers what he receives.

This gives Deuteronomy 18:18 an oral and recitational shape. At Sinai, Moses receives the Law in the form of tablets. Barnabas presents a different form of revelation to Jesus: in Barnabas 10, a book descends into the heart of Jesus; in Barnabas 167, Jesus says that God gave him a book like a clear mirror which came down into his heart, and that what he speaks comes forth from that book. Deuteronomy 18:18 points to commanded divine speech placed in the mouth: words received from God and then spoken by the prophet.

That profile matters when the passage is set beside the revelation associated with Prophet Muhammad. The Qur’an is not presented as a single written tablet handed down at once, but as divine speech revealed gradually, recited, heard, repeated, memorized, and delivered through the Prophet’s mouth across the course of his mission. The phrase My words in his mouth therefore fits the oral and recitational character of Muhammad’s revelation with unusual directness.

What Does Like Unto Thee Signify?

Deuteronomy 18:18 also says that the prophet will be like Moses. The comparison is not limited to receiving revelation in a general sense. Moses was a messenger who received divine speech, brought commandments, led a community, and formed a people under a revealed order.

• Receiving divine revelation: the prophet speaks words God places in his mouth.
• Delivering commandments: the prophet communicates what God commands rather than general moral advice.
• Leading a community: the Mosaic profile is communal and public, not limited to private inspiration.
• Establishing a legal and social order: Moses’ mission shaped worship, law, and communal life.
• Producing historical transformation: the prophet like Moses would be expected to leave a visible historical imprint.

Which Prophet Fits This Description?

John the Baptist does not fit this profile. He was a great prophet, yet he is not portrayed as one who established a legal-social order, governed a people, and led far-reaching historical transformation in the manner of Moses.

Jesus is central and exalted in the New Testament narrative; yet in the account of his earthly mission, he is not depicted as one who founded a Mosaic-style legal and social order and led his people within that framework in the manner of Moses.

By contrast, Prophet Muhammad — receiving revelation, delivering divine commandments, leading a community, establishing a legal and social order, and guiding major historical transformation during his own lifetime — emerges as the prophet who most conspicuously resembles Moses under these criteria.

The Christian Counter-Reading: Acts 3 and Acts 7

The clearest Christian counter-reading comes through Acts 3 and Acts 7, where Deuteronomy 18 is applied to Jesus:

For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.

Acts 7 repeats the same identification in Stephen’s speech:

This is that Moses, which said unto the children of Israel, ‘A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear.’

Acts plainly applies the passage to Jesus. The open question is whether that Christian application exhausts the wording of Deuteronomy 18 when it is read alongside John 1, Deuteronomy 34:10, the Torah’s brother-language, and the Abrahamic-Paran horizon.

Matthew 22 and Psalm 110: Existing Jewish and Christian Readings

Two main traditional responses stand behind this discussion. Christian interpretation usually accepts Matthew’s messianic premise and resolves the tension through a theological distinction: the Messiah is David’s son according to human descent, yet David’s Lord because of divine sonship, incarnation, pre-existence, or exaltation. That works within the wider Christian reading of Matthew, but the immediate wording of Matthew 22:41–46 does not state the distinction explicitly.

Jewish interpretation usually takes another route because Judaism does not read Matthew as Scripture. The discussion centers on Psalm 110 itself. Some Jewish readings argue that the second lord is a human term of honor, or that the Psalm is addressed to David or connected with Abraham rather than a divine Messiah. These readings may weaken Psalm 110 as an independent Christian proof-text, but they do not explain Matthew’s own narrative premise: Jesus is portrayed as silencing the Pharisees by showing that their Davidic answer cannot stand as a complete account on its own.

Matthew 22: David’s Lord and the Davidic Answer Under Pressure

With those readings on the table, Matthew 22 can be read at the level of its own exchange. It belongs here because it addresses the lineage question from the other side. Deuteronomy 18:18 raises the prophet’s brother-line; Matthew 22 asks whether David’s son is a sufficient account of the expected figure. Together they create one cumulative pressure: the brother-language cannot simply be collapsed into a narrow internal label, and the Davidic answer does not by itself exhaust the figure’s identity.

The setting matters. Matthew 22 is no calm academic exchange. The chapter first presents opponents trying to entangle Jesus in his words through questions about tribute to Caesar, resurrection, and the greatest commandment. Only after this sequence does Jesus turn the pressure back on the Pharisees: What do you think about the Christ? Whose son is he?

While the Pharisees were gathered together, Jesus asked them, saying, ‘What think ye of Christ? whose son is he?’ They say unto him, ‘The son of David.’ He saith unto them, ‘How then doth David in spirit call him Lord, saying, The LORD said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool? If David then call him Lord, how is he his son?’ And no man was able to answer him a word, neither durst any man from that day forth ask him any more questions.

The Psalm being cited is Psalm 110:1:

The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool.

Their answer comes at once: The son of David. Jesus then cites Psalm 110 and asks why David, speaking in the Spirit, calls this figure Lord. The passage ends by saying that no one was able to answer him, and from that day no one dared to question him further. That ending matters: Matthew presents the question not as a minor puzzle, but as the reply that silences the challengers.

A word-by-word reading of Matthew 22

The Greek sequence moves with unusual directness:

The linguistic detail is important. Jesus does not say, How is he merely David’s son? The word only or merely is not present. Nor does the exchange introduce a two-level distinction such as son according to flesh, Lord according to divinity. The immediate grammar moves more sharply: the Pharisees answer David’s son; Jesus asks how David can call this figure Lord. The question does not itself supply the harmonization; it places the easy Davidic answer under pressure. The exchange does not explicitly deny Davidic descent; it shows that David’s son is not, by itself, a complete answer.

How Deuteronomy 18:18 and Matthew 22 Fit Together

Deuteronomy 18:18 and Matthew 22 are bound by the same underlying question: through which line is the promised figure recognized? Deuteronomy opens the brother-language beyond a merely tribal label; Matthew shows that David’s son does not by itself exhaust the expected figure’s identity.

This carries the discussion back to Abraham. Before David, there was Abraham; within Abraham’s house, Ishmael belongs to the field of interpretation. If the prophet addresses Israel while arising from among Israel’s brothers, and the Davidic answer remains incomplete, the Ishmaelite reading stands within the biblical field rather than outside it.

Barnabas Adds One Further Step

Conclusion: A Reading Pressed by the Texts

No reader is asked to accept the Muslim identification at once. The more immediate point is that this reading does not arise from nowhere. It belongs to an Abrahamic field of language — Moses, brotherhood, spoken revelation, Ishmael, Paran, and the expectation of a coming figure who speaks what he receives.

Once these passages are read as pointing beyond their immediate settings toward a future prophet, the question becomes historical too. Across the long centuries after Jesus, no other known figure of comparable scale appears from the Abrahamic world with the same combination of received revelation, spoken scripture, law-bearing mission, and world-historical community that is associated with Prophet Muhammad.

Reference controls

The argument depends on wording and reception. Readers should therefore check both the primary biblical text and the major counter-readings: Jewish readings that keep Deuteronomy 18 within Israel's prophetic history, and Christian readings that apply the passage to Jesus in Acts 3 and Acts 7.

• Hebrew / interlinear controls: Deuteronomy 18:15–18; Deuteronomy 34:10; Deuteronomy 2:4–8; Deuteronomy 23:7; Genesis 17:20; Genesis 21:21; Deuteronomy 33:2.
• Jewish commentary control: Rashi on Deuteronomy 18:15, where the promise is read in relation to prophets raised for Israel from prophet to prophet.
• New Testament controls: John 1:19–25; Acts 3:22–26; Acts 7:37; Matthew 22:41–46; Psalm 110:1; John 16:13.
• Barnabas comparison: Gospel of Barnabas chapters 43–44 are used only as a later comparative witness to the Ishmael-line reading.
