1 Kings 11:5

For Solomon went after Ashtoreth the goddess of the Zidonians, and after Milcom the abomination of the Ammonites.

Ashtoreth - plural, Ashtaroth (Astarte), a female divinity worshipped by the Sidonians (1 Kings 11:33; 2 Kings 23:13) [Septuagint, tee Astratee (cf. Genesis 14:5), the moon].

Milcom (1 Kings 11:33; 2 Kings 23:13) - Molech, (see Mover's 'Die Religion und die Gottheiten der Phonizier,' p. 12, etc.) But though Milcom is commonly considered synonymous with Molech, and both were idolized by the Ammonites, there was a difference between them, not only in name, but in their place of worship (the former in a temple built on a mountain east of Jerusalem, the latter in the valley Hinnom), and in their rites, Molech being infamous for the immolation of children; but the rites of Milcom are unknown. Milcom, or Malcom, their king (Jeremiah 49:1; Jeremiah 49:3; Zephaniah 1:3; Amos 1:15), comes from the same root as Molech.
