Deuteronomy 27:1-27:10
Moses and the elders of Israel charged the people, saying: Observe all the Instruction that I enjoin upon you this day. As soon as you have crossed the Jordan into the land that the Lord your God is giving you, you shall set up large stones. Coat them with plaster and inscribe upon them all the words of this Teaching. When you cross over to enter the land that the Lord your God is giving you, a land flowing with milk and honey, as the Lord, the God of your fathers, promised you--upon crossing the Jordan, you shall set up these stones, about which I charge you this day, on Mount Ebal, and coat them with plaster. There, too, you shall build an altar to the Lord your God, an altar of stones. Do not wield an iron tool over them; you must build the altar of the Lord your God of unhewn stones. You shall offer on it burnt offerings to the Lord your God, and you shall sacrifice there offerings of well-being and eat them, rejoicing before the Lord your God. And on those stones you shall inscribe every word of this Teaching most distinctly.
Moses and the levitical priests spoke to all Israel, saying: Silence! Hear, O Israel! Today you have become the people of the Lord your God: Heed the Lord your God and observe His commandments and His laws, which I enjoin upon you this day.
