Joshua 1:12-15

Then Joshua addressed the Reubenites, the Gadites, and the half-tribe of Manasseh. He said, “Remember what Moses the servant of GOD commanded you: GOD, your God, gives you rest and he gives you this land. Your wives, your children, and your livestock can stay here east of the Jordan, the country Moses gave you; but you, tough soldiers all, must cross the River in battle formation, leading your brothers, helping them until GOD, your God, gives your brothers a place of rest just as he has done for you. They also will take possession of the land that GOD, your God, is giving them. Then you will be free to return to your possession, given to you by Moses the servant of GOD, across the Jordan to the east.”
