Deuteronomy 27:5-10

5Build an altar of stones there to the Lord your God — do not use any iron tool on them.

6Use uncut stones to build the altar of the Lord your God and offer burnt offerings to the Lord your God on it.

7There you are to sacrifice fellowship offerings, eat, and rejoice in the presence of the Lord your God.

8Write clearly all the words of this law on the plastered stones.”

9Moses and the Levitical priests spoke to all Israel, “Be silent, Israel, and listen! This day you have become the people of the Lord your God.

10Obey the Lord your God and follow his commands and statutes I am giving you today.”
