Topheth was an area in the valley of Ben-Hinnom, southwest of the city of David, leading into the Kidron Valley. People once practiced child sacrifice there.
Molech is linked to several gods (see 1 Kings 11:5, 7, 33) and is also associated with a sacrifice offered to Baal (Jeremiah 7:31–32; 19:5–6; 32:35).
