Malachi 3:9-11 (NIV)
9 You are under a curse—your whole nation—because you are robbing me. 10 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. 11 I will prevent pests from devouring your crops, and the vines in your fields will not drop their fruit before it is ripe,” says the Lord Almighty.
