Psalms 106:34-38

Psalms 106:34-38. They did not destroy the nations, concerning whom the LORD commanded them: but were mingled among the heathen, and learned their works. And they served their idols: which were a snare unto them. Yea, they sacrificed their sons and their daughters unto devils, and shed innocent blood, even the blood of their sons and of their daughters, whom they sacrificed unto the idols of Canaan: and the land was polluted with blood.

Just think how low they had sunk; God’s own people had come down to this, that they actually offered their own children in sacrifice to Moloch.
