4:8
At the end of chapter 3 we read of the destruction of Jerusalem. Here we read of the complete restoration. One should never assume that destruction is the end of the matter. This applies to the nation of Israel, we can also apply it to our own lives, or the lives of those we love and pray for. At times it can seem as of there is no hope, as if things have gone to far down hill, but with God this is never the case. The destiny of Jerusalem is to have dominion and kingship.
4:9
We then get a sudden change in tone again, we are back to the current judgement. Zion would have to go through much suffering. “Have you no king?” Israel and Judah did have kings, though not very good ones. The truth was that their true king was the Lord. This had always been the case, but they had sought to deny this truth. So human kings failed them. Eventually their true king did come, but they rejected Him. All this rejection of the Lord as king led to much suffering, both in Micah’s day and the years after that, and in the years after they crucified Christ.
4:10
Micah then foretells of the exile in Babylon. At the time Babylon was not the major power, that place belonged to Assyria. Though Babylon was on the radar, as we see in Isaiah 39. So Micah foretells the Babylonian captivity, and many of the people did indeed go off to Babylon as exiles. But this exile would not be the final destination, for they would be rescued from that place.
