Charles Ellicott Commentary Isaiah 10:19

"And the remnant of the trees of his forest shall be few, so that a child may write them." — Isaiah 10:19 (ASV)

And the rest of the trees of his forest shall be few. —To number an army, or to count the killed and wounded after a battle, was commonly the work of the royal scribe, who is so often depicted in that role in Assyrian sculptures. Here the survivors (the “remnant” as before) were to be so few (literally, a number) that even a boy who could hardly count except by using his fingers would be skilled enough to number them.
