Joshua 1:9 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. NKJV
These promises are addressed to Joshua individually, as the successor to Moses. The section begins and ends with God’s promise to be with him. Second and second-to-last in order is the exhortation to be strong and courageous. In the middle is the commandment to keep the law together with the promise of success if he does. In ch. 23 Joshua applies these ideas to the whole people of Israel in the light of the faithfulness of God that the whole book proclaims (Reformation Study Bible). The promise that God gave Joshua that day is no less true for us now. There is no need for fear when we lean on the powerful presence of the Lord.
