Jeremiah 19:4-6

19:4 I will do so because these people have rejected me and have defiled this place. They have offered sacrifices in it to other gods which neither they nor their ancestors nor the kings of Judah knew anything about. They have filled it with the blood of innocent children. 19:5 They have built places here for worship of the god Baal so that they could sacrifice their children as burnt offerings to him in the fire. Such sacrifices are something I never commanded them to make! They are something I never told them to do! Indeed, such a thing never even entered my mind! 19:6 So I, the Lord, say: “The time will soon come that people will no longer call this place Topheth or the Hinnom Valley. But they will call this valley the Valley of Slaughter!
