Psalm 106:34-38

They did not destroy the peoples, as the LORD commanded them, but they mixed with the nations and learned to do as they did. They served their idols, which became a snare to them. They sacrificed their sons and their daughters to the demons; they poured out innocent blood, the blood of their sons and daughters, whom they sacrificed to the idols of Canaan, and the land was polluted with blood.
