A few weeks ago, in the Sabbath Bible Lessons, The Light of the World (II), we just studied the sad experience of Achan.
Before the conquest of Jericho, God gave specific instructions to His people regarding the battle and the spoils. Since the victory belonged to the Lord, also the spoils should be consecrated to Him: “All the silver, and gold, and vessels of brass and iron, are consecrated unto the Lord: they shall come into the treasury of the Lord” (Joshua 6:19).
