Isaiah 10:19-20

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.
