Malaquias 3

8 Will a man rob God? yet ye rob me. But ye say, Wherein have we robbed thee? In tithes and offerings. 9 Ye are cursed with the curse; for ye rob me, even this whole nation. 10 Bring ye the whole tithe into the storehouse, that there may be meat in mine house, and prove me now herewith, saith the LORD of hosts, if I will not open you the windows of heaven, and pour you out a blessing, that there shall not be room enough to receive it.
