2:12,13 These verses may refer to the captivity of Israel and Judah. But the passage is also a prophecy of the conversion of the Jews to Christ. The Lord would not only bring them from captivity, and multiply them, but the Lord Jesus would open their way to God, by taking upon him the nature of man, and by the work of his Spirit in their hearts, breaking the fetters of Satan. Thus he has gone before, and the people follow, breaking, in his strength, through the enemies that would stop their way to heaven.
12. A sudden transition from threats to the promise of a glorious restoration. Compare a similar transition in Ho 1:9, 10. Jehovah, too, prophesies of good things to come, but not like the false prophets, "of wine and strong drink" (Mic 2:11). After I have sent you into captivity as I have just threatened, I will thence assemble you again (compare Mic 4:6, 7).
all of thee—The restoration from Babylon was partial. Therefore that here meant must be still future, when "all Israel shall be saved" (Ro 11:26). The restoration from "Babylon" (specified (Mic 4:10) is the type of the future one.
Jacob … Israel—the ten tribes' kingdom (Ho 12:2) and Judah (2Ch 19:8; 21:2, 4).
remnant—the elect remnant, which shall survive the previous calamities of Judah, and from which the nation is to spring into new life (Isa 6:13; 10:20-22).
as the sheep of Bozrah—a region famed for its rich pastures (compare 2Ki 3:4). Gesenius for Bozrah translates, "sheepfold." But thus there will be tautology unless the next clause be translated, "in the midst of their pasture." English Version is more favored by the Hebrew.
