Deuteronomy 31:1-5
Succession of Moses by Joshua
31:1 Then Moses went and spoke these words to all Israel.
31:2 He said to them, “Today I am a hundred and twenty years old. I am no longer able to get about, and the Lord has said to me, ‘You will not cross the Jordan.’
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.
