Joshua 1:14

Let your wives, and your children, and your cattle abide in the land which he hath given you; but you, all your able-bodied men, well equipt, shall cross over before your brethren, and assist them; until the Lord our God shall give your brethren rest, as well as you; until they possess the land which the Lord our God giveth them. Then you shall return, every one to his possession, which Moses gave you on the east side of the Jordan.
