Deuteronomy 31:6-8

6So be strong and courageous! Do not be afraid and do not panic before them. For the Lord your God will personally go ahead of you. He will neither fail you nor abandon you.”

7Then Moses called for Joshua, and as all Israel watched, he said to him, “Be strong and courageous! For you will lead these people into the land that the Lord swore to their ancestors he would give them. You are the one who will divide it among them as their grants of land.

8Do not be afraid or discouraged, for the Lord will personally go ahead of you. He will be with you; he will neither fail you nor abandon you.”
