That another oracle is in view is clear from the question and answer format that begins this pericope, as it does the others. Verse 17 contains the question and answer, and the discussion follows in 3:1-6. The Israelites' changeability (2:17) contrasts with Yahweh's constancy (3:6).
2:17 Malachi announced to his hearers that they had wearied God with their words; He was tired of hearing them say something. Their response was again hypocritical incredulity. They believed He could hardly be tired of listening to them since He had committed Himself to them as their covenant lord (cf. Isa. 40:28).31The prophet explained that Yahweh was tired of them saying that He delighted in them even though they said that everyone who did evil was acceptable to Him. They seem to have lost their conscience for right and wrong and assumed that because God did not intervene He approved of their sin. Really their question amounted to a challenge to God's justice. If they were breaking His law and He was just, He surely must punish them. Their return to the land indicated to them that He was blessing them, and He promised to bless the godly in the Mosaic Covenant (Deut. 28:1-14).
Modern people say the same thing. "If there is a just God, why doesn't He do something about all the suffering in the world?""If God is just, why do the wicked prosper?"Scripture reveals that God blesses the wicked as well as the righteous (Matt. 5:45; Acts 14:17), and the righteous suffer as well as the wicked because of the Fall and sin (Gen. 3:16-19; Eccles. 2:17-23). Moreover, God allows Satan to afflict the righteous as well as the wicked (Job 1-2). God will eventually punish the wicked and bless the righteous, but perhaps not in this life (cf. Job 21:7-26; 24:1-17; Ps. 73:1-14; Eccles. 8:14; Jer. 12:1-4; Hab. 1). Malachi's audience had forgotten part of what God had revealed on this subject, and, of course, they had not yet received New Testament revelation about it.
3:1 The Lord's response to the cynical Israelites was to point them to the future. He predicted the coming of His messenger (cf. Isa. 40:3-5). There is no question about who this was because Jesus identified him as John the Baptist (Matt. 11:10; cf. Mark 1:2; Luke 7:27). This future messenger would clear the way in preparation for Yahweh (cf. Isa. 40:3; John 1:23). Clearly Jesus Christ is Yahweh since John the Baptist prepared the way for Jesus.
Then the Lord, whom the Israelites were seeking, would suddenly come to His temple (cf. Ezek. 43:1-5; Zech. 8:3). Though Jesus entered the temple in Jerusalem many times during His earthly ministry, this sudden coming was not fulfilled then (cf. vv. 2-5). It will occur when He returns to set up His messianic kingdom. "The messenger of the covenant"is another name for the Lord who would come following the appearance of the first messenger promised in this verse. He would be the divine Messiah. "Messenger"means "angel,"and the Angel of the Lord is in view here. The "covenant"is the New Covenant that God promised to make with the Jews in the future (cf. Jer. 31:31-34; Ezek. 37:26). The Jews delighted in this Messenger because His coming had been a subject of messianic prophecy and an object of eager anticipation from early in Israel's history (Gen. 3:15; pass.). Sovereign Yahweh promised His coming again here. The Jews had been expressing disbelief that God would intervene and establish justice in the world (2:17), but God promised He would.
3:2-3 When the Lord came suddenly to His temple, no one would be able to stand before Him. Elsewhere the prophets foretold that this time would be a day of judgment on the whole world marked by disaster and death (4:1; Isa. 2:12; Joel 3:11-16; Amos 5:18-21; Zech. 1:14-18). Here Malachi said no one would be able to endure His coming because He would purify the priesthood, the people who stood closest to Him. As a fire He would burn up the impurities of the priests, and as a laundryman's soap He would wash them clean (cf. Isa. 1:25; Jer. 6:29-30; Ezek. 22:17-22; Zech. 3:5). The Levitical priests would then be able to offer sacrifices to Yahweh in a righteous condition rather than as they were in Malachi's day (cf. 1:6-2:9; Isa. 56:7; 66:20-23; Jer. 33:18; Ezek. 40:38-43; 43:13-27; 45:9-25; Zech. 14:16-21). The multiple figures of cleansing and the repetition of terms for cleansing stress the thoroughness of the change that the Lord's Messenger would affect.
3:4 After this cleansing of the priests, Judah and Jerusalem (i.e., all Israel) would be able to offer sacrifices that would please the Lord, in contrast to the present ones that did not (cf. 1:13-14). They would be acceptable like the offerings the priests offered earlier in Israel's history, before the priesthood had become corrupt.
3:5 At that time the Lord assured His people that He would draw near to them, but it would be for judgment. He would quickly judge all types of sin that they practiced, whereas in Malachi's day, and now, He waits to judge (cf. 2 Pet. 3:9-10). The Levites would not be the only Jews He judged; all the Israelites living then would come under His judgment (cf. Ezek. 20:34-38). He would judge them for all types of activity forbidden for His people: sorcery, adultery, lying, oppression of employees, widows, orphans, mistreatment of aliens, even all forms of irreverence for Him. This was His answer to their claim that He was unjust (2:17).
3:6 The Lord concluded by reminding His people of one of His character qualities that should have made them fear Him and have hope. He does not change, and that is why they would not be consumed totally. He was faithful to His covenant promises in the Abrahamic and Mosaic Covenants; He would never destroy them completely but would chasten them and finally bless them. By calling the Jews "sons of Jacob,"the Lord was connecting their behavior with that of their notorious patriarch. Promises are only as good as the person who makes them, so the fact that Yahweh does not change strengthens the certainty of their fulfillment (cf. Deut. 4:31; Ezek. 36:22-32).32
The statement that Yahweh does not change (cf. 1 Sam. 15:29; Heb. 13:8) may seem to contradict other statements that the Lord changed His mind (e.g., Exod. 32:14). This statement that He does not change refers to the essential character of God. He is always holy, loving, just, faithful, gracious, merciful, etc. The other statements, that He changes, refer to His changing from one course of action to another. They involve His choices, not His character. If He did not change His choices, He would not be responsive; if He changed His character, He would be unreliable.33
