What does Malachi 3:2 mean?
Israel's complaint about God's judgment (Malachi 2:17) is short-sighted. Worse, it's hypocritical. God's judgment is powerful, and applies to all people, not merely "other people," as Israel seems to think. This verse asks a rhetorical question about who, among men, can withstand the judgment of God. The assumed answer, of course, is that no one can.Two analogies are used here to describe God's judgment. Precious metals are refined using fire. Materials like gold and silver melt, but don't burn, at temperatures where other materials burst into flames. Heating these metals destroys impurities, leaving only the pure alloy. God's judgment is often symbolized by fire for this reason (Malachi 4:1).
Various translations of the Hebrew term bo'rit mekabbesim all include the same basic idea: cleansing. The reference is to a form of lye, or potash, an extremely strong soap. This is the kind of material used to dissolve impurities and bleach clothes. Just as the refiner's fire removes what is impure, destroying what's undesirable, so too does this "fullers' soap" wash away stains and spots.
Verse 3 will remind readers that God's first priority for purification will be the priesthood (Malachi 2:3–4).
