The biblical figure from the Book of Joshua who is stoned to death in the Valley of Achor is Achan.
In Joshua 7, Achan of the tribe of Judah secretly takes items devoted to destruction after the Israelites capture Jericho: a Babylonian-style robe, silver, and a bar of gold. His disobedience is blamed for Israel’s defeat at the nearby city of Ai.
Joshua identifies the culprit through a tribal selection process. Achan confesses that he saw, coveted, and hid the forbidden goods beneath his tent. The Israelites then bring him and his possessions to the Valley of Achor, where the biblical account says he is stoned and the stolen goods are destroyed.
A common mix-up is the spelling: Achan is also rendered Achar in some translations and in 1 Chronicles 2:7. The name Achor is associated with “trouble,” reflecting the story’s explanation for the valley’s name. Joshua 15:7 later places the valley on Judah’s northern border.
