Albert Barnes Commentary Isaiah 8:15

"And many shall stumble thereon, and fall, and be broken, and be snared, and be taken." — Isaiah 8:15 (ASV)

And many among them - Many by the invasion under the Assyrian. Many were taken captive; many killed, and many were carried to Babylon. The repetition here of so many expressions so nearly synonymous is emphatic, and shows that it would certainly be done.
