Malachi 3:8

5 And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against the false swearers, and against those that oppress the hireling in his wages, the widow, and the fatherless, and that turn aside the sojourner from his right, and fear not me, saith Jehovah of hosts.

6 For I, Jehovah, change not; therefore ye, O sons of Jacob, are not consumed.

7 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?

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 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.

11 And I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast its fruit before the time in the field, saith Jehovah of hosts.
