Misgab

Height, a town of Moab, or simply, the height=the citadel, some fortress so called; or perhaps a general name for the highlands of Moab, as some think (Jer. 48:1). In Isa. 25:12, the word is rendered “high fort.”

(height), a place in Moab. (Jeremiah 48:1) It appears to be mentioned also in (Isaiah 25:12) thorough there rendered in the Authorized Version "high fort."

mis'-gab (ha-misgabh; Codex Vaticanus Amath; Codex Alexandrinus to krataioma): Named with Nebo and Kiriathaim in the denunciation of doom against Moab (Jer 48:1). No trace of any name resembling this has been found. Possibly we should take it, not as a place-name, but as an appellation of some strong fortress, perhaps of Kir-moab itself. The term is elsewhere translated "high fortress" (Isa 25:12, etc.).
