Deuteronomy 4:44-46

44This is God's Law that Moses explained to the Israelites.

45These are the rules, the teaching and the commands that Moses taught the Israelites after they had left Egypt.

46At that time they were in the valley near to Beth-Peor, on the east side of the Jordan River. That was in the land of Sihon, king of the Amorites, who ruled in Heshbon. Moses and the Israelites had attacked him after they came out of Egypt.
