Isaiah
Isaiah 2:19ESV·traditional attribution

And people shall enter the caves of the rocks and the holes of the ground, from before the terror of the LORD, and from the splendor of his majesty, when he rises to terrify the earth.

John Calvin Reformed @genevareformer

19. And they shall enter into the holes of the rocks He had formerly used other words when addressing them in the second person, Enter into the rock, (verse 10,) that he might inflict a severer stroke on their minds.

Matthew Henry Presbyterian @wholebiblehenry

The prophet here goes on to show what a desolation would be brought upon their land when God should have forsaken them. This may refer particularly to their destruction by the Chaldeans first, and afterwards by the Romans, or it may have a general respect to the method God takes to awaken and humble proud sinners, and to put them out of conceit with that...

John Gill Reformed Baptist @doctorgill

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, &c. See Gill on Isa 2:10, Isa 2:19.
