'Caves' in the Bible

And the hand of Midian prevailed against Israel: and because of the Midianites the children of Israel made them the dens which are in the mountains, and caves, and strong holds.

When the men of Israel saw that they were in a strait, (for the people were distressed,) then the people did hide themselves in caves, and in thickets, and in rocks, and in high places, and in pits.

To dwell in the clifts of the valleys, in caves of the earth, and in the rocks.

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.

Say thou thus unto them, Thus saith the Lord GOD; As I live, surely they that are in the wastes shall fall by the sword, and him that is in the open field will I give to the beasts to be devoured, and they that be in the forts and in the caves shall die of the pestilence.

(Of whom the world was not worthy:) they wandered in deserts, and in mountains, and in dens and caves of the earth.
