Joshua 1: 9-11

9 Have I not commanded you? Be strong and courageous. Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.” 10 And Joshua commanded the officers of the people, 11 “Pass through the midst of the camp and command the people, ‘Prepare your provisions, for within three days you are to pass over this Jordan to go in to take possession of the land that the Lord your God is giving you to possess.’”
