Deuteronomy 27:5-7

New English Translation

⁵ Then you must build an altar there to the Lord your God, an altar of stones—do not use an iron tool on them. ⁶ You must build the altar of the Lord your God with whole stones and offer burnt offerings on it to the Lord your God. ⁷ Also you must offer fellowship offerings and eat them there, rejoicing before the Lord your God.
