Deuteronomy 3:15-3:22
To Machir I assigned Gilead. And to the Reubenites and the Gadites I assigned the part from Gilead down to the wadi Arnon, the middle of the wadi being the boundary, and up to the wadi Jabbok, the boundary of the Ammonites.
[We also seized] the Arabah, from the foot of the slopes of Pisgah on the east, to the edge of the Jordan, and from Chinnereth down to the sea of the Arabah, the Dead Sea.
At that time I charged you, saying, "The Lord your God has given you this country to possess. You must go as shock-troops, warriors all, at the head of your Israelite kinsmen. Only your wives, children, and livestock--I know that you have much livestock--shall be left in the towns I have assigned to you, until the Lord has granted your kinsmen a haven such as you have, and they too have taken possession of the land that the Lord your God is assigning them, beyond the Jordan. Then you may return each to the homestead that I have assigned to him."
I also charged Joshua at that time, saying, "You have seen with your own eyes all that the Lord your God has done to these two kings; so shall the Lord do to all the kingdoms into which you shall cross over. Do not fear them, for it is the Lord your God who will battle for you."
