Psalms 106:34-38

They did not destroy the peoples as the LORD had commanded them, but they mingled with the nations and adopted their customs. They worshiped their idols, which became a snare to them. They sacrificed their sons and their daughters to false gods. They shed innocent blood, the blood of their sons and daughters, whom they sacrificed to the idols of Canaan, and the land was desecrated by their blood.
