Jeremiah 19:6

He also defiled Topheth, which is in the valley of the son of Hinnom, that no man might make his son or his daughter pass through the fire for Molech.

For Topheth has long been ready, Indeed, it has been prepared for the king. He has made it deep and large, A pyre of fire with plenty of wood; The breath of Yahweh, like a torrent of brimstone, sets it afire.

“Therefore, behold, days are coming,” declares Yahweh, “when it will no longer be called Topheth or the valley of the son of Hinnom, but the valley of the Slaughter; for they will bury in Topheth because there is no other place.

“But they put their detestable things in the house which is called by My name, to defile it.

and I pronounced them unclean because of their gifts, in that they caused all their firstborn to pass through the fire so that I might make them desolate, in order that they might know that I am Yahweh.”’
