Deuteronomy 31:6 - 31:8
6 Be strong and courageous. Do not be afraid or be in dread of them, for Yahweh your God is the one who goes with you. He will not fail you or forsake you.” 7 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 Yahweh has sworn to their fathers to give them, and you shall give it to them as an inheritance. 8 And Yahweh is the one who goes ahead of you; He will be with you. He will not fail you or forsake you. Do not fear or be dismayed.”
5 No man will be able to stand before you all the days of your life. Just as I have been with Moses, I will be with you; I will not fail you or forsake you.
