Deuteronomy 27:1-3

The Assembly at Shechem

27:1 Then Moses and the elders of Israel commanded the people: “Pay attention to all the commandments I am giving you today. 27:2 When you cross the Jordan River to the land the Lord your God is giving you, you must erect great stones and cover them with plaster. 27:3 Then you must inscribe on them all the words of this law when you cross over, so that you may enter the land the Lord your God is giving you, a land flowing with milk and honey just as the Lord, the God of your ancestors, said to you.
