1“Behold, I send my messenger, and he will prepare the way before me! The Lord, whom you seek, will suddenly come to his temple. Behold, the messenger of the covenant, whom you desire, is coming!” says Yahweh of Armies. 2“But who can endure the day of his coming? And who will stand when he appears? For he is like a refiner’s fire, and like launderers’ soap; 3and he will sit as a refiner and purifier of silver, and he will purify the sons of Levi, and refine them as gold and silver; and they shall offer to Yahweh offerings in righteousness. 4Then the offering of Judah and Jerusalem will be pleasant to Yahweh as in the days of old and as in ancient years.
5I will come near to you to judgment. I will be a swift witness against the sorcerers, against the adulterers, against the perjurers, and against those who oppress the hireling in his wages, the widow, and the fatherless, and who deprive the foreigner of justice, and don’t fear me,” says Yahweh of Armies.
6“For I, Yahweh, don’t change; therefore you, sons of Jacob, are not consumed. 7From the days of your fathers you have turned away from my ordinances and have not kept them. Return to me, and I will return to you,” says Yahweh of Armies. “But you say, ‘How shall we return?’
8Will a man rob God? Yet you rob me! But you say, ‘How have we robbed you?’ In tithes and offerings. 9You are cursed with the curse; for you rob me, even this whole nation. 10Bring the whole tithe into the storehouse, that there may be food in my house, and test me now in this,” says Yahweh of Armies, “if I will not open you the windows of heaven, and pour you out a blessing, that there will not be enough room for. 11I 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 its time in the field,” says Yahweh of Armies. 12“All nations shall call you blessed, for you will be a delightful land,” says Yahweh of Armies.
13“Your words have been harsh against me,” says Yahweh. “Yet you say, ‘What have we spoken against you?’ 14You have said, ‘It is vain to serve God,’ and ‘What profit is it that we have followed his instructions and that we have walked mournfully before Yahweh of Armies? 15Now we call the proud happy; yes, those who work wickedness are built up; yes, they tempt God, and escape.’
16Then those who feared Yahweh spoke one with another; and Yahweh listened and heard, and a book of memory was written before him for those who feared Yahweh and who honored his name. 17They shall be mine,” says Yahweh of Armies, “my own possession in the day that I make. I will spare them, as a man spares his own son who serves him. 18Then you shall return and discern between the righteous and the wicked, between him who serves God and him who doesn’t serve him.
In the time of Malachi the prophet, the priests had “corrupted” the ministry entrusted to them (Mal 2:1-9). They offered blemished sacrifices on behalf of the people (Mal 1:6-14), although they had ample instruction not to do so (Lev 22:17-25; Deut 15:21). They refused to teach the people the word of God, the fear of God, repentance toward God, and walking with God (Mal 2:5-7). They showed “partiality in the instruction,” meaning that they taught the parts of Scripture they wanted and ignored other parts (2:8-9). Men divorced their wives and married others who worshiped foreign gods (2:10-16). The people practiced sorcery, adultery, false oaths, and oppression (3:5). They also robbed the Lord by withholding tithes and contributions (3:8-12).
As a result, the priests and the people did not trust the love of God (1:2), challenged the prophet whether they actually despised and defiled the name of the LORD (1:6-7, 12-13), received a curse from God (2:2; 3:10-12), questioned the justice of God (2:17), and asserted that it was vain to serve God (3:14).
Jesus and His apostles taught similarly of the dangers that ministers can bring on themselves and on those who follow them. He said, “Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves (Matt 7:13-23),” and, “they are blind guides of the blind. And if a blind man guides a blind man, both will fall into a pit (Matt 15:14; see also Matthew 23).” Peter warned, “There will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction upon themselves (2 Peter 2:1).” Because of the gravity of the office of teacher, James also admonished us, “Let not many of you become teachers, my brethren, knowing that as such we shall incur a stricter judgment (James 3:1).” For further study, consult Jer 23-29, Ezek 13 and 34, and Acts 20:17-38.
