Deuteronomy 31:7-8

7Then Moses called for Joshua and said to him in the presence of all Israel, “Be strong and courageous, for you will go with this people into the land that the LORD swore to their fathers to give them, and you shall give it to them as an inheritance. 8The LORD Himself goes before you; He will be with you. He will never leave you nor forsake you. Do not be afraid or discouraged.”
