Deuteronomy 27:1-3

Then Moses and the responsible men of Israel gave the people these orders: Keep all the orders which I have given you this day; And on the day when you go over Jordan into the land which the Lord your God is giving you, put up great stones, coating them with building-paste, And writing on them all the words of this law, after you have gone over; so that you may take the heritage which the Lord your God is giving you, a land flowing with milk and honey, as the Lord, the God of your fathers, has said.
