The Prophet Moses Said Would Come After Him

Moses stood before Israel and said: stop asking God to speak to you. That is what Deuteronomy 18 is really about, and most readers miss it entirely.

When the Israelites gathered at Horeb, they begged God not to speak to them directly. The fire was too great. The voice was too much. Let me not hear the voice of God again, they said, lest I die (Deuteronomy 18:16). So God agreed. He would send a prophet instead. And Moses, standing at the edge of his own life, passed on the promise: a prophet will rise from among your own people, one like me, and through him God will continue to speak.

The Aramaic translation known as Targum Onkelos renders this passage with remarkable precision. Onkelos, working in the first century CE in Babylon, preserves the verse without alteration but surrounds it with careful interpretive work. His approach to Deuteronomy 18 reveals what the ancient translators understood that modern readers often overlook: the chapter is not primarily about sorcery. It is about what Israel does instead of sorcery. It is about what replaces the forbidden knowledge of diviners and enchanters. It is about prophecy as the only legitimate channel between heaven and earth.

The chapter opens by establishing the Levites' inheritance. They receive no land. God is their portion. Onkelos explains this practically: the gifts of the priesthood, the tithes, the offerings, the priestly shares from every household in Israel. That ground-level detail matters because it frames the whole chapter. The priest sustains the community's material life. The prophet sustains its spiritual life. These are parallel institutions, both divinely appointed, both essential.

Then comes the prohibition. No one in Israel may pass sons or daughters through fire. No divination, no sorcery, no snake charming, no consulting the dead. Onkelos names each forbidden practice with clinical specificity. He is describing a religious technology that the surrounding nations used constantly: ways of learning what was hidden, of knowing the future, of influencing fate. Israel must reject all of it.

Not because knowledge is dangerous. Because the wrong source of knowledge is dangerous.

The Sifrei Devarim, a tannaitic legal midrash on Deuteronomy compiled in second-century Palestine, asks the obvious question: what makes a prophet like Moses? What does that standard actually mean? According to that tradition, it means a prophet who stands between God and the people, who receives the divine word directly rather than through dreams or visions, who speaks face to face with God rather than through riddles. Moses was the measuring rod. Every prophet after him would be judged against that standard.

Targum Jonathan on Deuteronomy 18, a Palestinian Aramaic translation from roughly the same period as Onkelos, adds a layer that the Hebrew text does not contain. Where the Torah simply forbids sorcery, Targum Jonathan enumerates specific forbidden practices with unsettling precision, naming people who make magical knots and bindings, who consult serpents, who attempt to communicate with the dead through ritual means. The Targum Jonathan tradition imports the number twenty-four as the count of priestly gifts, grounding the spiritual office in economic reality: the Levites receive exactly this much, no more, and the specificity matters because it makes the covenant legible and enforceable.

What Onkelos does with the promise of the coming prophet is theologically careful. He renders it without embellishment, without the added interpretive layers that Targum Jonathan sometimes supplies. The verse stands: a prophet from your midst, like me, God will establish for you. And when that prophet speaks, God says, I will place My words of prophecy in his mouth (Deuteronomy 18:18). The prophet is not the source. The prophet is the vessel. The Memra, God's divine Word, passes through the prophet to the people.

That distinction mattered enormously in the world Onkelos inhabited. By the first century CE, Israel had survived the destruction of the Second Temple. The priestly system had collapsed. What remained? Torah. And the chain of transmission that had carried Torah from Sinai through the prophets to the rabbinic courts. Onkelos's entire translation is built around the idea that God does not speak from the sky directly to trembling crowds. God speaks through text, through teachers, through the interpretive chain that stretches back to Moses himself.

Moses told Israel: you asked me to stand between you and God. I agreed. But I will not always be here. When I am gone, watch for the prophet who carries that same weight. And if a prophet speaks in God's name and the word does not come to pass, do not fear him (Deuteronomy 18:22). The tradition has its own immune system.

It has been working for three thousand years.
