Deuteronomy 3:16-18

Amplified Bible

¹⁶ To the Reubenites and Gadites I gave the territory from Gilead as far as the Valley of Arnon, with the middle of the Valley as a boundary, and as far as the Jabbok River, the boundary of the sons of Ammon; ¹⁷ the Arabah also, with the Jordan as its boundary, from Chinnereth (the Sea of Galilee) as far as the sea of the Arabah, the Salt Sea (Dead Sea), at the foot of the slopes of Pisgah on the east.

¹⁸ “Then I commanded you [Reuben, Gad, and the half-tribe of Manasseh] at that time, saying, ‘The Lord your God has given you this land to possess; all you who are brave men shall cross over [the Jordan] armed before your brothers, the sons of Israel.
