Deuteronomy 3:18-22 - Instructions To The Transjordanian Tribes
18 "Then I commanded you at that time, "The Lord your God gave you this land as a possession. Those equipped for battle every man a warrior will cross before your fellow Israelis. 19 However, your women, children, and livestock and I know you have many may reside in your towns that I gave you 20 until the LORD grants rest to your fellow Israelis like you. When they take possession of the territory that the LORD your God is about to give them on the other side of the Jordan River, then each of you may return to the territory that I've allotted for you.'
21 "I also charged Joshua at that time, "You witnessed everything that the LORD your God did to the two kings. Indeed, the LORD will do this to all the kingdoms which you are about to enter. 22 You are not to fear them, because the LORD your God will fight for you.'"
