the land is defiled
Leviticus 18:25
18:25 the land is defiled. The land of Canaan, which had long before been promised by God to Abraham and his seed, had become so defiled by the time of Joshua that God was completely vindicated in ordering the extermination of its incorrigibly wicked inhabitants, lest the people of Israel and eventually the whole world be corrupted by their influence, as in the world before the flood. This chapter gives a representative listing of their pervasive sins–promiscuity, incest, homosexuality, bestiality, even burning their children in sacrifice to a pagan god (Leviticus 18:21) and blaspheming the true God. God had been long-suffering for four hundred years, but now their iniquity was full and their time was up (note Genesis 15:13-16).
