Christian image of the 8th commandment. God knows that if we don't live according to the 10 Commandments there will be such utter chaos in the world that eventually we would be living not much higher than the animals. Thou shalt not steal is important so that we will control our covetousness. We want for all that we can get, but God keeps us in check by telling us that we can't have it unless we pay for it ourselves. This creates a work ethic in us to go to work, be diligent and then make our purchases.
