Deuteronomy 31:3-6

Context
31:3 As for the Lord your God, he is about to cross over before you; he will destroy these nations before you and dispossess them. As for Joshua, he is about to cross before you just as the Lord has said. 31:4 The Lord will do to them just what he did to Sihon and Og, the Amorite kings, and to their land, which he destroyed. 31:5 The Lord will deliver them over to you and you will do to them according to the whole commandment I have given you. 31:6 Be strong and courageous! Do not fear or tremble before them, for the Lord your God is the one who is going with you. He will not fail you or abandon you!”
