Josh. 15, 8, valley of Hinnom, of the sons
of Hinnom, etc. on the south and west
of Jerusalem, through which passed the
southern boundary of Benjamin and the
northern of Judah, Josh. 15,8. 18, 16. It
was noted for the human sacrifices here
offered to Moloch, 2 K. Jer. 11. 
Moloch, sometimes Ba'al Moloch, known as the Sacred Bull, was widely worshipped in the ancient Near East and wherever Punic culture extended (including, but not limited to, the Ammonites, Edomites and the Moabites). Baal Moloch was conceived under the form of a calf or an ox or depicted as a man with the head of a bull.
Hadad, Baal or simply the King identified the god within his cult. The name Moloch is the name he was known by among his worshippers, but is a Hebrew translation. (MLK has been found on stele at the infant necropolis in Carthage). The written form Μολώχ Moloch (in the Septuagint Greek translation of the Old Testament), or Molek (Hebrew), is no different than the word Melech or king, transformed by interposing the vowels of bosheth or 'shameful thing'.
