Deuteronomy 27:2-3

MSB(i) 2 And on the day you cross the Jordan into the land that the LORD your God is giving you, set up large stones and coat them with plaster. 3 Write on them all the words of this law when you have crossed over to enter the land that the LORD your God is giving you, a land flowing with milk and honey, just as the LORD, the God of your fathers, has promised you.
