'Caves' in the Bible

And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth.

At that time men will throw their silver and gold idols, which they made for themselves to worship, into the caves where rodents and bats live,

They will go into the caves of the rocksand the crevices in the cliffs,away from the terror of the Lordand from His majestic splendor,when He rises to terrify the earth.

For the palace shall be deserted, the multitude of the city shall be forsaken; hill and watchtower shall be caves for ever, a joy of wild asses, a pasture of flocks;

But this is a people plundered and despoiled;All of them are trapped in caves,Or are hidden away in prisons;They have become a prey with none to deliver them,And a spoil, with none to say, “Give them back!”

Who sit among the graves [trying to conjure up evil spirits] and spend the night in the secret places [where spirits are thought to dwell];Who eat swine’s flesh,And their pots hold the broth of unclean meat;
