Deuteronomy 9:4

9:4 Do not think to yourself after the Lord your God has driven them out before you, “Because of my own righteousness the Lord has brought me here to possess this land.” It is because of the wickedness of these nations that the Lord is driving them out ahead of you.

Deuteronomy 31:3

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.
