Achan, or Achar. [Heb. Akan, meaning uncertain, and Akar, "troubler."] A Judahite who, against the explicit command of God that all of Jericho was to be devoted to God, appropriated to himself a Babylonian garment, a piece of gold, and a quantity of silver from the spoil of the city. His act brought a curse upon the whole nation and caused the defeat of the Israelites at Ai. As punishment he and his family were stoned to death and all his property was destroyed (Jos 7:1-26; 22:20; 1 Chr 2:7) -- Seventh-day Adventist Bible Dictionary.
