Malachi 3:7-10

From the days of your fathers ye have turned aside from mine ordinances, and have not kept them. Return unto me, and I will return unto you, saith Jehovah of hosts. But ye say, Wherein shall we return? Will a man rob God? yet ye rob me. But ye say, Wherein have we robbed thee? In tithes and offerings. Ye are cursed with the curse; for ye rob me, even this whole nation. Bring ye the whole tithe into the store-house, that there may be food in my house, and prove me now herewith, saith Jehovah 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.
