Deuteronomy 31:5

³The Lord thy God who goes before thee, he shall destroy these nations before thee, and thou shalt inherit them: and it shall be Joshua that goes before thy face, as the Lord has spoken.

⁴And the Lord thy God shall do to them as he did to Sihon and Og the two kings of the Amorites, who were beyond Jordan, and to their land, as he destroyed them.

— Deuteronomy 31:5 —

⁶Be courageous and strong, fear not, neither be cowardly, neither be afraid before them; for it is the Lord your God that advances with you in the midst of you, neither will he by any means forsake thee, nor desert thee.

⁷And Moses called Joshua, and said to him before all Israel, Be courageous and strong; for thou shalt go in before this people into the land which the Lord swore to your fathers to give to them, and thou shalt give it to them for an inheritance.
