Deuteronomy 31:6-7, 23

Be strong and courageous, do not be afraid or tremble at them, for the LORD your God is the one who goes with you. He will not fail you or forsake you.” Then Moses called to Joshua and said to him in the sight of all Israel, “Be strong and courageous, for you shall go with this people into the land which the LORD has sworn to their fathers to give them, and you shall give it to them as an inheritance.

Then He commissioned Joshua the son of Nun, and said, “Be strong and courageous, for you shall bring the sons of Israel into the land which I swore to them, and I will be with you.”
