Joshua 1:13-15

“Remember what Moses, the servant of the LORD, commanded you: ‘The LORD your God is giving you a place of rest. He has given you this land.’ Your wives, children, and livestock may remain here in the land Moses assigned to you on the east side of the Jordan River. But your strong warriors, fully armed, must lead the other tribes across the Jordan to help them conquer their territory. Stay with them until the LORD gives them rest, as he has given you rest, and until they, too, possess the land the LORD your God is giving them. Only then may you return and settle here on the east side of the Jordan River in the land that Moses, the servant of the LORD, assigned to you.”
