Joshua 1:13; Joshua 1:15

13 "Remember what the LORD's servant Moses commanded you. Moses said, 'The LORD your God will give you this land--a place to rest.'

15 take possession of the land the LORD your God is going to give them. Then they will have a place to rest like you do. After that, you may go back and take possession of the land east of the Jordan River which the LORD's servant Moses gave you."
