Deuteronomy 27:6-10

You shall build the altar of the Lord your God of uncut stones, and you shall offer on it burnt offerings to the Lord your God;

and you shall sacrifice peace offerings and eat there, and rejoice before the Lord your God.

You shall write on the stones all the words of this Law very clearly.”

Then Moses and the Levitical priests spoke to all Israel, saying, “Be silent and listen, Israel! This day you have become a people for the Lord your God.

So you shall obey the Lord your God, and do His commandments and His statutes which I am commanding you today.”
