Deuteronomy 31:7-8

7Then Moses called to Joshua and said to him in the sight of all Israel, “1Be 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. 82The Lord is the one who goes ahead of you; He will be with you. 3He will not fail you or forsake you. Do not fear or be dismayed.”
