JAHAZAH or JAHZAH, a city in the north of Moab, near which Moses defeated Sihon, Numbers 21:23. It was in the limits of Reuben, and was a Levitical city, Joshua 21:36. In Isaiah 15:4, and Jeremiah 48:21, it appears as again in the hands of the Moabites.

Trodden down (called also Jahaza, Joshua 13:18; Jahazah, 21:36; Jahzah, 1 Chronicles 6:78), a town where Sihon was defeated, in the borders of Moab and in the land of the Ammonites beyond Jordan, and north of the river Arnon (Numbers 21:23; Deuteronomy 2:32). It was situated in the tribe of Reuben, and was assigned to the Merarite Levites (Joshua 13:18; 21:36). Here was fought the decisive battle in which Sihon (q.v.) was completely routed, and his territory (the modern Belka) came into the possession of Israel. This town is mentioned in the denunciations of the prophets against Moab (Isaiah 15:4; Jeremiah 48:34).
