What does God have to say about it?
"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. I will prevent pests from devouring your crops, and the vines in your fields will not drop their fruit because it is ripe," says the LORD Almighty. "Then all the nations will call you blessed, for yours will be a delightful land," says the LORD Almighty.
