Charles Ellicott Commentary Isaiah 2:19

"And men shall go into the caves of the rocks, and into the holes of the earth, from before the terror of Jehovah, and from the glory of his majesty, when he ariseth to shake mightily the earth." — Isaiah 2:19 (ASV)

And they shall go into the holes of the rocks. —The imagery of the earthquake in Uzziah’s reign (see Note on Isaiah 2:10) is still present to Isaiah’s thoughts. (See Revelation 6:15.)

When he ariseth to shake terribly the earth. —The Hebrew verb and noun have the emphasis of a paronomasia which cannot be reproduced in English, but of which the Latin “ut terreat terram” gives some idea.
