Deuteronomy 27:5-10

5Build an altar of stones there dedicated to the Lord your God. Don’t use an iron chisel on the stones.

6You must use uncut stones to build the altar of the Lord your God. Sacrifice burnt offerings on it to the Lord your God.

7Sacrifice fellowship offerings, eat them there, and enjoy yourselves in the presence of the Lord your God.

8Write clearly and carefully all the words of these teachings on the stones you set up.”

9Then Moses and the Levitical priests said to all Israel, “Be quiet and listen, Israel. Today you have become the people of the Lord your God.

10Obey the Lord your God and follow his commands and laws which I’m giving you today.”
