JAHAZ (in 1Ch_6:78, Jer_48:21Jahzah).—A town at which Sihon was defeated by Israel (Num_21:23, Deu_2:32, Jdg_11:20). After the crossing of the Arnon, messengers were sent to Sihon from the ‘wilderness of Kedemoth’ (Deu_2:26), and he ‘went out against Israel into the wilderness and came to Jahaz’ (Num_21:23). Jahaz is mentioned in connexion with Kedemoth (Jos_13:18; Jos_21:36). These passages indicate a position for Jahaz in the S. E. portion of Sihon’s territory. Jahaz was one of the Levite cities of Reuben belonging to the children of Merari (Jos_13:18; Jos_21:36 (see note in RVm [Note: Revised Version margin.] ], 1Ch_6:78). According to the Moabite Stone (11:18–20), the king of Israel dwelt at Jahaz while at war with king Mesha, but was driven out, and the town was taken and added to Moabite territory. Isaiah (Isa_15:4) and Jeremiah (Jer_48:21; Jer_48:34) refer to it as in the possession of Moab. The site has not yet been identified.
