(composed of the names of two Syrian idols), the name of a place in the valley of Megiddo. It is alluded to by the prophet Zechariah (Zec 12:11) in a proverbial expression derived from the lamentation for Josiah, who was mortally wounded near this place (2Ch 35:22-25). It has been identified with the modern Rummaneh, a village "at the foot of the Megiddo hills, in a notch or valley about an hour and a half south of Tell Metzellim."
