2 Kings 23:10

23:10 The king ruined Topheth in the Valley of Ben Hinnom so that no one could pass his son or his daughter through the fire to Molech.

Jeremiah 7:31-32

7:31 They have also built places of worship in a place called Topheth in the Valley of Ben Hinnom so that they can sacrifice their sons and daughters by fire. That is something I never commanded them to do! Indeed, it never even entered my mind to command such a thing! 7:32 So, watch out!” says the Lord. “The time will soon come when people will no longer call those places Topheth or the Valley of Ben Hinnom. But they will call that valley the Valley of Slaughter and they will bury so many people in Topheth they will run out of room.

Jeremiah 19:2-6

19:2 Go out to the part of the Hinnom Valley which is near the entrance of the Potsherd Gate. Announce there what I tell you. 19:3 Say, ‘Listen to what the Lord says, you kings of Judah and citizens of Jerusalem! The Lord God of Israel who rules over all says, “I will bring a disaster on this place that will make the ears of everyone who hears about it ring! 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!

Jeremiah 19:13

19:13 The houses in Jerusalem and the houses of the kings of Judah will be defiled by dead bodies just like this place, Topheth. For they offered sacrifice to the stars and poured out drink offerings to other gods on the roofs of those houses.’”
