Deuteronomy 27:6-8

New Catholic Bible

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. ⁸ You will write all of the words of the law upon these stones in a very clear manner.
