A'chor (Heb. Akor', עָכוֹר, trouble; Sept. Α᾿χωρ), the name of a valley (עֵמֶק, Sept. φάραγξ, κοιλάς, ῎Eμεκ) not far from Jericho, given in consequence of the trouble occasioned to the Israelites by the sin of Achan (q.v.), who was stoned to death and buried there (Jos 7:24,26). It was known by the same name in the time of Jerome (Onomast. s.v.). The prophets more than once allude to it typically in predicting the glorious changes under the Messiah, either on account of its proverbial fertility (Isa 65:10) or by way of contrast with the unfortunate entrance of the Israelites near this pass into Canaan on their first approach (Ho 2:15). It was situated on the boundary of Judah and Benjamin, between the stone of Ben-Bonan and Debir, south of Gilgal (Jos 15:7), and was probably the same now called (see Zimmerman's Map) Wady Dabr, running into the Dead Sea east of Ain Jehair (Robinson's Researches, 2, 254). SEE TRIBE. Thomson (Land and Book, 2, 185) says vaguely that "it runs up from Gilgal toward Bethel;" but this is inconsistent with the above notices of location (comp. Keil, Comment. on Joshua p. 201). SEE CHERITH.
