Achan may have been identified through the use of the Urim and Thummim, a God-given method for casting sacred lots (objects used to seek God’s decision). These items remained in the care of the high priest, probably kept in a bag or pouch (see Exodus 28:30; Numbers 27:21). They may have been two objects of different colors, possibly stones or gems. People asked questions in a way that required a “yes” or “no” answer.
