Moses begins with the Levitical priests. The tribe of Levi will receive no portion of land like the other tribes; the Lord is their inheritance. They will live from portions of the sacrifices, from the firstfruits of grain, wine and oil, and from the first wool of the sheep. A Levite living in any town of Israel who wants to serve at the place the Lord chooses may do so and share equally with his brothers.
Moses then warns that, once in the land, Israel must not imitate the abominations of the nations. He lists what is forbidden: making children pass through the fire, divination, sorcery, omens, witchcraft, spells, consulting mediums and spiritists, and seeking the dead. God is driving out those nations precisely because of these practices, and his people must be blameless before him.
Instead of diviners, God will give Israel prophets. Moses recalls that at Horeb the people, terrified by God's voice, asked never to hear it directly again. The Lord promises to raise up from among their brothers a prophet like Moses, put his words in his mouth, and hold accountable anyone who does not listen. But a prophet who speaks in God's name something God has not commanded, or who speaks in the name of other gods, will die. If someone asks how to recognize a word the Lord has not spoken, the sign is that what is announced in the Lord's name does not come true; that prophet spoke presumptuously and is not to be feared.
