Micah speaks of the LORD assembling Jacob and gathering the remnant of Israel. He compares them to a flock in a fold, and says their king passes on before them, with the LORD at their head (Micah 2:12–13).
In Micah 2:12–13 the speaker promises a decisive regathering of “Jacob” and “the remnant of Israel.” The people are pictured as a dense flock crowded into a safe pasture, loud with the sound of many persons. Then the scene shifts to movement: a “breaker” goes ahead, the people burst through an exit gate, and their king leads them out. These two verses close a section dominated by sharp accusations against those who plan wrongdoing and seize land and homes (2:1–2), and by warnings that disaster will answer that injustice (2:3–5). The chapter also depicts conflict between Micah’s message and voices that want smoother speech (2:6–11).
Micah 2:12–13 presents a strong promise of reversal after a stretch of judgment language. The speaker (in the flow of the book, this is best heard as Yahweh speaking) says he will assemble and gather “Jacob” and “the remnant of Israel.” The point is not just survival of a few individuals, but a re-formed people.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Micah 2:12-13, then read the surrounding section so the answer stays connected to the passage's flow.
12I will surely assemble, Jacob, all of you; I will surely gather the remnant of Israel; I will put them together as the sheep of Bozrah, as a flock in the midst of their pasture; they shall make great noise by reason of [the multitude of] men.
13The breaker is gone up before them: they have broken forth and passed on to the gate, and are gone out thereat; and their king is passed on before them, and Yahweh at the head of them.
