What man committed such a terrible sin that Joshua executed his entire family?
Achan (rhymes with bacon). When the Jews destroyed Jericho, they weren’t supposed to take anything—everything in Jericho belonged to God. Achan stole 200 silver coins, a bar of gold, and a robe imported from Babylon (now Iraq). His disobedience cost the Jews their next battle. Joshua ordered Achan and his entire family stoned to death and burned. You can read the story in Joshua 7:19-26.
