Deuteronomy 31:3, 7, 23

It is the LORD your God who will cross ahead of you; He will destroy these nations before you, and you shall dispossess them. Joshua is the one who will cross ahead of you, just as the LORD has spoken.

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.”
