Joshua 1:14-15

14Your wives, your little ones, and your cattle shall remain in the land which Moses gave you beyond the Jordan, but you shall cross before your brothers in battle array, all your valiant warriors, and shall help them, 15until the Lord gives your brothers rest, as He gives you, and they also possess the land which the Lord your God is giving them. 1Then you shall return to 2your own land, and possess 3that which Moses 4the servant of the Lord gave you beyond the Jordan toward the sunrise.”
