Deuteronomy 31:7-8

7Moses then summoned Joshua and said to him in the sight of all Israel, “Be strong and courageous, for you will go with this people into the land the Lord swore to give to their ancestors. You will enable them to take possession of it.

8The Lord is the one who will go before you. He will be with you; he will not leave you or abandon you. Do not be afraid or discouraged.”
