Achor

Achor - meaning trouble in Hebrew, 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, but in modern times the valley is often considered to be the wadi al-Qelt, a deep ravine located to Jericho's south.
The Book of Joshua, chapter seven, relates the story from which the valley's name comes. After the problems the Israelites had as a result of Achan's immoral theft of items commanded to be destroyed, the Israelite community stoned Achan and his household. Liberal scholars and archaeologists regard the narrative about Achan as an aetiological myth , and instead suspect that it gained this name for another reason. 
Due to the horrific nature of this narrative, the phrase valley of trouble became eminently proverbial and occurs elsewhere in the Hebrew bible. The Book of Isaiah and Book of Hosea use the term - the valley of trouble, a place for herds to lie down in (Isaiah 65:10), the valley of trouble for a door of hope (Hosea 2:15) as a way of describing the redemption promised by God.
