Malachi 3: 8-12

Will a man rob God? Yet you rob me. "But you ask, 'How do we rob you?' "In tithes and offerings. You are under a curse—the whole nation of you—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 you will not have room enough for it. I will prevent pests from devouring your crops, and the vines in your fields will not cast their fruit," says the LORD Almighty. "Then all the nations will call you blessed, for yours will be a delightful land," says the LORD Almighty.
