(3) Sons of Levi.--Meaning especially the priests, the sons of Aaron, son of Amram, son of Kohath, son of Levi (Exodus 6:16-20); for judgment must begin at the house of God. (Comp. Jeremiah 25:29; Ezekiel 9:6; 1Peter 4:17.)

In righteousness refers rather to the moral character of the offerer than to the nature of the sacrifices, as being such as were prescribed by the Law. This and the following verse do not, of course, imply that there are to be material sacrifices in Messianic times. The prophet speaks in such language as was suitable to the age in which he lived. (See Note on Malachi 1:11.)

Verse 3. - He shall sit. As a judge. The prophet confines himself to the first of the two images presented in the preceding verse. The sons of Levi. Especially the priests, who ought to set an example, and teach holiness and obedience. Thus judgment should begin at the house of God (Ezekiel 9:6; 1 Peter 4:17). The purifying consists not only in exterminating the evil, but also in correcting and improving all who are not wholly incorrigible. We may call to mind Christ's purging of the temple, and his denunciations of the teaching body among the Jews, and see herein his way of trying his ministers in all ages, that they may shine like lights in the world, and adorn the doctrine of God in all things. That they may offer (and they shall be offering) unto the Lord an offering (minchah) in righteousness. The pure sacrifice shall then be offered with a pure heart. As firstfruits of this improved condition, we read in Acts 6:7, "A great company of the priests were obedient to the faith."

3:1-6 The first words of this chapter seem an answer to the scoffers of those days. Here is a prophecy of the appearing of John the Baptist. He is Christ's harbinger. He shall prepare the way before him, by calling men to repentance. The Messiah had been long called, He that should come, and now shortly he will come. He is the Messenger of the covenant. Those who seek Jesus, shall find pleasure in him, often when not looked for. The Lord Jesus, prepares the sinner's heart to be his temple, by the ministry of his word and the convictions of his Spirit, and he enters it as the Messenger of peace and consolation. No hypocrite or formalist can endure his doctrine, or stand before his tribunal. Christ came to distinguish men, to separate between the precious and the vile. He shall sit as a Refiner. Christ, by his gospel, shall purify and reform his church, and by his Spirit working with it, shall regenerate and cleanse souls. He will take away the dross found in them. He will separate their corruptions, which render their faculties worthless and useless. The believer needs not fear the fiery trial of afflictions and temptations, by which the Saviour refines his gold. He will take care it is not more intense or longer than is needful for his good; and this trial will end far otherwise than that of the wicked. Christ will, by interceding for them, make them accepted. Where no fear of God is, no good is to be expected. Evil pursues sinners. God is unchangeable. And though the sentence against evil works be not executed speedily, yet it will be executed; the Lord is as much an enemy to sin as ever. We may all apply this to ourselves. Because we have to do with a God that changes not, therefore it is that we are not consumed; because his compassions fail not.And he shall sit as a refiner, and purifier of silver,.... Kimchi interprets this, as he does the latter part of the preceding verse Malachi 3:2, of the day, and not of the Lord, which he compares to a judge that sits and separates the guilty from the innocent; see 1 Corinthians 3:13 but it is to be understood of the Lord himself, and expresses his diligence in sitting and separating good men and principles from bad ones, just as silver is purified and refined from dross. Maimonides (a) understands the passage of the Messiah; for he says,

"in the days of the King Messiah, when his kingdom is restored, and all Israel shall be gathered to him, all will have their genealogies set right by his mouth, through the Holy Spirit that rests upon him, as it is said, "he shall sit a refiner and purifier":''

as a refiner sits and observes his metal while it is melting, and waits the proper time to pour it out and separate the dross from it; so Christ is here represented as sitting, while his people are purifying and refining by the various ways and means he makes use of: it denotes the continued care of Christ over them; his eye is upon them, that nothing be lost but their dross and corruption; and his patience in waiting to be gracious to them, and do them good; and his diligent attention to the proper season of doing it; designing by all that he does, not their hurt and damage, but their real good, for he saves them, though it be by fire; and indeed every trial and affliction is for the purifying of their souls, and the brightening of their graces, and increasing their spiritual experience, light, and knowledge.

And he shall purify the sons of Levi; the priests, either literally understood, some of these were converted from their evil principles and practices, and became obedient to the doctrines of the Gospel, Acts 6:7 or figuratively, the apostles of Christ and ministers of the Gospel, who were made clean by him; or rather all the people of God, who are made priests as well as kings, and are a royal priesthood, and are purified by Christ, both by his blood, and the imputation of his righteousness, by which they become without spot and blemish, and as white as snow; and by the Spirit in sanctification, he sprinkling clean water upon them, and purifying their hearts by faith in the blood of Jesus; and also by afflictive dispensations of Providence sanctified unto them. Mention is made of the priests and Levites, because these were so very corrupt in the times of Christ, and as appears from the preceding chapters.

And purge them as gold and silver; are purged in the fire from their dross: this shows of what worth and value, and in what esteem the Lord's people are to him; he reckons of them as gold and silver, and as his peculiar treasure: and it suggests, that before conversion they are joined unto and mixed with wicked men, comparable to dross; and that they have in them the dross, corruption, and impurity of sin; which is original and natural to them, and inherent in them, and which can only be removed by the grace of God and blood of Christ.

That they may offer unto the Lord an offering in righteousness; themselves, their bodies and souls; the sacrifices of prayer, praise, and alms deeds; to the offering up of which in righteousness, in sincerity and truth, in an upright way, it is necessary that a person should be purified by the blood of Christ, and sanctified by the grace of his Spirit.
