19There will be very few trees left in those forests; even a child will be able to count them.”
20In the future there will be only a few people left in Israel; not many descendants of Jacob will still be alive. But they will no longer rely on the king of Assyria, the king of the nation that tried to destroy them. Instead, they will faithfully/sincerely trust in Yahweh, the Holy One of Israel.
21Those Israelis will return to their mighty God.
22Now, the people of Israel are as numerous as the grains of sand on the seashore, but only a few of them will return from the countries to which they were exiled. Yahweh has decided to destroy most of the Israelis and that is what he must do because he is completely just/righteous.
