"Will a mere mortal rob God? Yet you rob me.  "But you ask, 'How are we robbing you?' "In tithes and offerings. You are under a curse - your whole nation - because you are robbing me.  Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this,"says the LORD Almighty, " and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it.  Malachi 3: 8-10  (NIV)
