Jahaz

trodden down (called also Jahaza, Josh. 13:18; Jahazah, 21:36;
Jahzah, 1 Chr. 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 (Num. 21:23; Deut. 2:32). It was
situated in the tribe of Reuben, and was assigned to the
Merarite Levites (Josh. 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 (Isa. 15:4; Jer. 48:34).
