Deuteronomy 27:1-8

¹Then Moses and the elders of Israel charged the people, saying, “Keep all the commandments which I command you today. ²So it shall be on the day when you cross the Jordan to the land which the Lord your God gives you, that you shall set up for yourself large stones and coat them with lime ³and write on them all the words of this law, when you cross over, so that you may 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, promised you. ⁴So it shall be when you cross the Jordan, you shall set up on Mount Ebal, these stones, as I am commanding you today, and you shall coat them with lime. ⁵Moreover, you shall build there an altar to the Lord your God, an altar of stones; you shall not wield an iron tool on them. ⁶You shall build the altar of the Lord your God of uncut stones, and you shall offer on it burnt offerings to the Lord your God; ⁷and you shall sacrifice peace offerings and eat there, and rejoice before the Lord your God. ⁸You shall write on the stones all the words of this law very distinctly.”
