[3] And he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the LORD an offering in righteousness. [4] Then shall the offering of Judah and Jerusalem be pleasant unto the LORD, as in the days of old, and as in former years. [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 false swearers, and against those that oppress the hireling in his wages, the widow, and the fatherless, and that turn aside the stranger from his right, and fear not me, saith the LORD of hosts. [6] For I am the LORD, I change not; therefore ye sons of Jacob are not consumed. [7] Even from the days of your fathers ye are gone away from mine ordinances, and have not kept them. Return unto you, saith the LORD of hosts. But ye said, Wherein shall we return? [8] 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. [13] Your words have been stout against me, saith the LORD. Yet ye say, What have we spoken [14] Ye have said, It is vain to serve God: and what profit is it that we have kept his ordinance, and that we have walked mournfully before of hosts?
