Hadadrimmon:

ha-dad-rim'-on, had-ad-rim'-on (hadhadh rimmon): A name which occurs, along with Megiddon, in Zec 12:11. It was long thought that this was a place in the plain of Megiddo, and that the mourning referred to was that for Josiah, slain in battle with Pharaoh-necoh (2Ki 23:29). This last, however, was certainly at Jerusalem. Jerome (Comm. on Zec) identifies Hadadrimmon with Maximianopolis, a village near Jezreel, probably Legio, the ancient Megiddo. Possibly, however, the form "Hadadrimmon" has arisen through the combination of two divine names; and the weeping may be that for Tammuz (Eze 8:14), with whom the old Semitic deity had become confused in the popular mind.
