Deuteronomy 9:1, 4

Hear, Israel: You are now about to cross the Jordan to go in and dispossess nations greater and stronger than you, with large cities that have walls up to the sky.

After the LORD your God has driven them out before you, do not say to yourself, “The LORD has brought me here to take possession of this land because of my righteousness.” No, it is on account of the wickedness of these nations that the LORD is going to drive them out before you.
