Deuteronomy 27:3-5

Revised Standard Version

³ and you shall write upon them all the words of this law, when you pass over to enter the land which the Lord your God gives you, a land flowing with milk and honey, as the Lord, the God of your fathers, has promised you. ⁴ And when you have passed over the Jordan, you shall set up these stones, concerning which I command you this day, on Mount Ebal, and you shall plaster them with plaster. ⁵ And there you shall build an altar to the Lord your God, an altar of stones; you shall lift up no iron tool upon them.
