Achor

Achor /ˈeɪkər/ (Hebrew עכור "muddy, turbid: gloomy, dejected") is the name of a valley in the vicinity of Jericho.

Eusebius (in Onomasticon) and Jerome (in Book of Sites and Names of Hebrew Places) implied that they thought it was a valley north of Jericho. In the nineteenth century some writers identified the valley with the wadi al-Qelt, a deep ravine located to Jericho's south. In the twentieth century the Hyrcania valley (El-Buqei'a in Arabic) west and south of Qumran, and Wadi en-Nu'eima have also been suggested. One difficulty is that the narrative of Joshua 7 appears to place the valley of Achor to the north of Jericho, between Jericho and Ai; but Joshua 15:7 makes the valley part of the boundary between the tribe of Judah and the tribe of Benjamin, to the south of Jericho, but not as far south as El-Buqei'a.
