Numbers 33:50-52

The Lord spake—ye shall drive out— i.e. Entirely root out and destroy the inhabitants, for their idolatry and abominable vices, Exodus 23:33.Deuteronomy 20:16; Deuteronomy 20:20. As they were shortly to pass into the promised land, God commands Moses to give the Israelites a general but strict notice, how they should treat the inhabitants of that land, as the instruments of his just providence in the punishment of their long and incurable course of wickedness; and for preventing themselves from being tainted and misled, by their vicious example, into any superstitious practices. See this command, delivered by Moses, Deuteronomy 7:1; Deuteronomy 7:26. Respecting the word pictures, and their images and high places, see Leviticus 1:17 and Exodus 23:24.
