Deuteronomy 31:2–8

²And he said to them, “I am a hundred and twenty years old this day; I am no longer able to go out and come in. The Lord has said to me, ‘You shall not go over this Jordan.’ ³The Lord your God himself will go over before you; he will destroy these nations before you, so that you shall dispossess them; and Joshua will go over at your head, as the Lord has spoken. ⁴And the Lord will do to them as he did to Sihon and Og, the kings of the Amorites, and to their land, when he destroyed them. ⁵And the Lord will give them over to you, and you shall do to them according to all the commandment which I have commanded you. ⁶Be strong and of good courage, do not fear or be in dread of them: for it is the Lord your God who goes with you; he will not fail you or forsake you.”

⁷Then Moses summoned Joshua, and said to him in the sight of all Israel, “Be strong and of good courage; for you shall go with this people into the land which the Lord has sworn to their fathers to give them; and you shall put them in possession of it. ⁸It is the Lord who goes before you; he will be with you, he will not fail you or forsake you; do not fear or be dismayed.”
