Deuteronomy 27:2–8

²And it shall be, on the day ^awhen you cross over the Jordan to the land which the Lord your God is giving you, that ^byou shall set up for yourselves large stones, and whitewash them with lime. ³You shall write on them all the words of this law, when you have crossed over, that you may enter the land which the Lord your God is giving you, ^c‘a land flowing with milk and honey,’ just as the Lord God of your fathers promised you. ⁴Therefore it shall be, when you have crossed over the Jordan, that ^don Mount Ebal you shall set up these stones, which I command you today, and you shall whitewash them with lime. ⁵And there you shall build an altar to the Lord your God, an altar of stones; ^eyou shall not use an iron tool on them. ⁶You shall build with ¹whole stones the altar of the Lord your God, and offer burnt offerings on it to the Lord your God. ⁷You shall offer peace offerings, and shall eat there, and ^frejoice before the Lord your God. ⁸And you shall ^gwrite very plainly on the stones all the words of this law.”
