Jer 31:31., but the covenant of Jehovah with Israel, according to which Jehovah dwells in the midst of Israel, and manifests His gracious presence by blessing the righteous and punishing the ungodly (cf. Exo 25:8; Lev 25:11-12; Deu 4:24; Isa 33:14): (Koehler). The words “Behold he (the covenant angel) cometh” serve to confirm the assurance, and are still further strengthened by אמר יי צ (saith Jehovah of hosts). This promise was fulfilled in the coming of Christ, in whom the angel of the covenant, the Logos, became flesh, and in the sending of John the Baptist, who prepared the way for Him. (See also at Mal 4:6)
Verses 2-4
With the coming of the Lord the judgment will also begin; not the judgment upon the heathen, however, for which the ungodly nation was longing, but the judgment upon the godless members of the covenant nation. Mal 3:2. “And who endures the day of His coming? and who can stand at His appearing? for He is like the smelter's fire, and like washers' lye: Mal 3:3. And will sit smelting and purifying silver, and will purify the children of Levi, and refine like gold and silver, that they may be offering to Jehovah His sacrifice in righteousness. Mal 3:4. And the sacrifice of Judah and Jerusalem will be pleasant, as in the days of the olden time, and as in the years of the past.” The question “who endures the day” has a negative meaning, like מי in Isa 53:1 : no one endures it (for the fact itself compare Joe 2:11). The prophet is speaking to the ungodly. The second clause is synonymous. עמד, to remain standing, in contrast with falling, or sinking under the burden of the judgment. The reason for this is given in the second hemistich. The Lord when He comes will be like a smelter's fire, which burns out all the corrupt ingredients that are mixed with the gold and silver (cf. Zec 13:9), and like the lye or alkaline salt by which clothes are cleansed from dirt (cf. Isa 4:4). The double figure has but one meaning; hence only the first figure is carried out in Mal 3:3, a somewhat different turn being given to it, since the Lord is no longer compared to the fire, but represented as a smelter. As a smelter purifies gold and silver from the dross adhering to it, so will the Lord refine the sons of Levi, by whom the priests are principally intended. The yâshabh (sit) serves as a pictorial description, like ‛âmad (stand) in
