God instructed them that when the walls came down, they were to go into the city and kill everything, both people and animals, and they were not to keep anything. (Any gold and silver they found were commanded to be put in the treasury of the Tabernacle.) Unfortunately, one man named Achan was not committed to unity in this part of the mission. He decided he would take of the items that were off-limits, and he hid them in his tent.
