Achor (â'kor), trouble. A valley near Jericho, where Achan was stoned; and from the trouble Achan brought upon Israel it had its name. Joshua 7:24; Joshua 7:26. Yet from that trouble sanctified a new career of victory began. With this idea we find the place and the circumstance afterwards adverted to. Hosea 2:15. The valley of trouble was the door through which Israel entered Canaan first; and again through the valley of trouble would the Lord lead his ransomed people to peace and rest. The boundary line of Judah ran by Achor. Joshua 15:7. It is also mentioned in Isaiah 65:10.
