Deuteronomy 31:3-6

LXX2012(i) 3 The Lord your God who goes before you, he shall destroy these nations before you, and you shall inherit them: and [it shall be] Joshua that goes before your face, as the Lord has spoken. 4 And the Lord your God shall do to them as he did to Seon and Og the two kings of the Amorites, who were beyond Jordan, and to their land, as he destroyed them. 5 And the Lord has delivered them to you; and you⌃ shall do to them, as I charged you. 6 Be 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 you, nor desert you.
