Isaiah 2:19, 21

They [the stricken, deprived of all in which they had trusted] will go into the caves of the rocks And into the holes of the ground [fleeing] From the terror and dread of the LORD And from the splendor of His majesty, When He arises to terrify the earth. [Luke 23:30]

To go into the caverns of the rocks and into the clefts of the [ragged] cliffs [as they flee] From the terror and dread of the LORD and the splendor of His majesty, When He arises to terrify the earth.
