mef'-a-ath, me-fa'-ath (mepha`ath and meypha`ath, mopha`ath; Codex Vaticanus, Maiphaath, Mephaath): A city of the Amorites in the territory allotted to Reuben, named with Kedemoth and Kiriathaim (Jos 13:18), and given to the Merarite Levites (Jos 21:37; 1Ch 6:79). It appears again as a Moabite town in Jer 48:21. It was known to Eusebius and Jerome (Onom) as occupied by a Roman garrison, but the site has been lost.
