Deuteronomy 31:6-7, 23

Be strong and courageous. Do not fear or be in dread of them, for it is the LORD your God who goes with you. He will not leave you or forsake you.” Then Moses summoned 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 that the LORD has sworn to their fathers to give them, and you shall put them in possession of it.

And the LORD commissioned Joshua the son of Nun and said, “Be strong and courageous, for you shall bring the people of Israel into the land that I swore to give them. I will be with you.”
