Zechariah 13:9
9. through . . . fire—of trial (Ps 66:10; Am 4:11; 1Co 3:15; 1Pe 1:6, 7). It hence appears that the Jews' conversion is not to precede, but to follow, their external deliverance by the special interposition of Jehovah; which latter shall be the main cause of their conversion, combined with a preparatory inward shedding abroad in their hearts of the Holy Spirit (Zec 12:10-14); and here, "they shall call on My name," in their trouble, which brings Jehovah to their help (Ps 50:15).
my people— (Jer 30:18-22; Eze 11:19, 20; Ho 2:23). Malachi 3:3
3. sit—The purifier sits before the crucible, fixing his eye on the metal, and taking care that the fire be not too hot, and keeping the metal in, only until he knows the dross to be completely removed by his seeing his own image reflected (Ro 8:29) in the glowing mass. So the Lord in the case of His elect (Job 23:10; Ps 66:10; Pr 17:3; Isa 48:10; Heb 12:10; 1Pe 1:7). He will sit down to the work, not perfunctorily, but with patient love and unflinching justice. The Angel of the Covenant, as in leading His people out of Egypt by the pillar of cloud and fire, has an aspect of terror to His foes, of love to His friends. The same separating process goes on in the world as in each Christian. When the godly are completely separated from the ungodly, the world will end. When the dross is taken from the gold of the Christian, he will be for ever delivered from the furnace of trial. The purer the gold, the hotter the fire now; the whiter the garment, the harder the washing [MOORE].
purify . . . sons of Levi—of the sins specified above. The very Levites, the ministers of God, then needed cleansing, so universal was the depravity. that they may offer . . . in righteousness—as originally (Mal 2:6), not as latterly (Mal 1:7-14). So believers, the spiritual priesthood (1Pe 2:5). 1 Peter 1:7
7. Aim of the "temptations."
trial—testing, proving. That your faith so proved "may be found (aorist; once for all, as the result of its being proved on the judgment-day) unto (eventuating in) praise," &c., namely, the praise to be bestowed by the Judge. than that of gold—rather, "than gold." though—"which perisheth, YET is tried with fire." If gold, though perishing (1Pe 1:18), is yet tried with fire in order to remove dross and test its genuineness, how much more does your faith, which shall never perish, need to pass through a fiery trial to remove whatever is defective, and to test its genuineness and full value? glory—"Honor" is not so strong as "glory." As "praise" is in words, so "honor" is in deeds: honorary reward. appearing—Translate as in 1Pe 1:13, "revelation." At Christ's revelation shall take place also the revelation of the sons of God (Ro 8:19, "manifestation," Greek, "revelation"; 1Jo 3:2, Greek, "manifested . . . manifested," for "appear . . . appear").
