This should put it to rest

Malachi 3:8-12 KJV
Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings.

[9] Ye are cursed with a curse: for ye have robbed me, even this whole nation.

[10] Bring ye all the tithes 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 .

[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 her fruit before the time in the field, saith the Lord of hosts.

[12] And all nations shall call you blessed: for ye shall be a delightsome land, saith the Lord of hosts.
