Deuteronomy 27:5-7

5And there you shall build an altar to the Lord your God, an altar of stones. aYou shall wield no iron tool on them; 6you shall build an altar to the Lord your God of uncut
Hebrew whole
stones. And you shall offer burnt offerings on it to the Lord your God,
7and you shall sacrifice peace offerings and cshall eat there, and you dshall rejoice before the Lord your God.
