Could indeed be separate incidents, as you say. Bottom line, though, is that Israel survives whatever gets thrown at them from here on in:
Amos 9:14 And I will bring again the captivity of my people of Israel, and they shall build the waste cities, and inhabit them; and they shall plant vineyards, and drink the wine thereof; they shall also make gardens, and eat the fruit of them. 15 And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the LORD thy God.
