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).
