Ga'ash (Heb. idעשׁ ׃-G, a shaking or earthquake; Sept. Γααρ Γά), a "bill" (rather mount ר ם-h) among the mountains of Ephraim, near Timnath-serah, on the north side of which Joshua was buried (Jos 24:30; Sept. Γαλα; Jg 2:9). Hence "the brooks of Gaash," i.e., the valleys or watercourses חִלַים -n, wadys, Sept. Ναχα… ρ Ναχα) around the mountain, which were the native place of Hiddai or Hurai, one of David's warriors (2Sa 23:30; 1Ch 11:32). Eusebius and Jerome merely state that Joshua's tomb was still a remarkable monument near Timnah in their day (Onomast. s.v. Γαασ, Gaas). SEE JOSHUA. If Timnath (q.v.) be the modern Tibnah, then Matthew Gaash is probablthe hill full of sepulchral caverns now facing it on the south. SEE EPHIAIM, MT.
