(Σινμαλκουή v.r. Εἰμαλκουαί , etc.; Vulg. Emalchuel, Malchus; Josephus, Μάλχος, Ant. 13, 5, 1; comp. 14, 14. 1; War, 1, 14, 1), an Arabian chief who had charge of Antiochus, the young son of Alexander Balas, before he was put forward by Tryphon as a claimant to the Syrian throne (1 Maccabees 11:39). According to Diodorus (Eclog. 32, 1) the name of the chief was Diocles, though in another place (Frag. 21, Muller) he calls him Jamblichus. The name evidently contains the element melek, "king," but the original form is uncertain (comp. Grotius and Grimm on 1 Macc. loc. cit).
