In the Hebrew Bible, Tophet or Topheth (Biblical Hebrew: תֹּפֶת, romanized: Tōp̄eṯ; Greek: Ταφέθ, translit. taphéth; Latin: Topheth) is a location in Jerusalem in the Valley of Hinnom (Gehenna), where worshipers engaged in a ritual involving "passing a child through the fire", most likely child sacrifice. Traditionally, the sacrifices have been ascribed to a god named Moloch. The Bible condemns and forbids these sacrifices, and the tophet is eventually destroyed by king Josiah, although mentions by the prophets Jeremiah, Ezekiel, and Isaiah suggest that the practices associated with the tophet may have persisted.
