Deuteronomy 27:5-7

New Catholic Bible

⁵ Build an altar there to the Lord, your God, an altar of stone. Do not use any iron tool upon them. ⁶ Build an altar of unhewn stones there to the Lord, your God. You shall offer your burnt offerings to the Lord, your God, there. ⁷ You are also to offer up peace offerings and eat them there, rejoicing in the presence of the Lord, your God.
