Joshua 1:9-11 (NKJV)
⁹  Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed, for the LORD your God is with you wherever you go.”
¹⁰  Then Joshua commanded the officers of the people, saying,
¹¹  “Pass through the camp and command the people, saying, ‘Prepare provisions for yourselves, for within three days you will cross over this Jordan, to go in to possess the land which the LORD your God is giving you to possess.’ ”
