trouble, a valley near Jericho, so called in consequence of the trouble which the sin of Achan caused Israel ( Joshua 7:24 Joshua 7:26 ). The expression "valley of Achor" probably became proverbial for that which caused trouble, and when Isaiah ( Isaiah 65:10 ) refers to it he uses it in this sense: "The valley of Achor, a place for herds to lie down in;" i.e., that which had been a source of calamity would become a source of blessing. Hosea also ( Hosea 2:15 ) uses the expression in the same sense: "The valley of Achor for a door of hope;" i.e., trouble would be turned into joy, despair into hope. This valley has been identified with the Wady Kelt.
