Deuteronomy 31:7-8

Then Moses called Joshua and said to him in the sight of all Israel, “Be strong and of good courage, for you must go with this people to the land which the LORD has sworn to their fathers to give them, and you shall cause them to inherit it. And the LORD, He is the One who goes before you. He will be with you, He will not leave you nor forsake you; do not fear nor be dismayed.”
