Hastings' Dictionary of the Bible (1898)
MEON'ENIM, THE PLAIN OF (oak of soothsayers), an oak or terebinth, Jud 9:37; comp. Deut 18:10, 2 Kgs 22:14; Mic 5:12, "soothsayers." The meaning of the name seems to connect it with some old diviners, probably of the pagan inhabitants. Conder suggests its identity with the plain of Mukhiah.
