Isaiah 2:21

21 And he shall enter into [the] chinks, either crazings, of stones, and into the caves of hard rocks, from the face of the inward dread of the Lord, and from the glory of his majesty, when he shall rise to smite the land. (And he shall enter into the crevices of stone, and into the caves of hard rock, from the fear of the Lord, and the glory of his majesty, when he shall rise to strike the land.)

Isaiah 2:21 Meaning and Commentary

Isaiah 2:21

To go into the clifts of the rocks, and into the tops of
the ragged rocks
That is, the idolaters shall either go there themselves; or they shall cause their idols to go there, thither they shall cast them; though the former sense seems the best, because of what follows, for fear of the Lord (See Gill on Isaiah 2:10) (See Gill on Isaiah 2:19).
