Isaiah 2:21

to enter the caverns of the rocks and the clefts of the cliffs , from before the terror of the Lord , and from the splendor of his majesty , when he rises to terrify the earth .

They will flee to caverns in the rocks and to the overhanging crags from the fearful presence of the Lord and the splendor of his majesty, when he rises to shake the earth.

To go into the clefts of the rocks, and into the tops of the ragged rocks, for fear of the Lord, and for the glory of his majesty, when he ariseth to shake terribly the earth.
