Deuteronomy 4:44-49

Moses starts to teach God's Law to the Israelites

44 This is God's Law that Moses explained to the Israelites. 45 These are the rules, the teaching and the commands that Moses taught the Israelites after they had left Egypt. 46 At 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. 47 They took power over his land, as well as the land of Og, king of Bashan. These two Amorite kings ruled on the east side of the Jordan river. 48 Their land went from Aroer, on the edge of the Arnon valley, as far as Mount Sirion (that is Mount Hermon). 49 This land included all the Jordan valley on the east side of the river, as far south as the Salt Sea, near Mount Pisgah.

4:49The Salt Sea is called the Dead Sea today.
