'Rocks' in the Bible

And they shall go into the caves of the rocks, and into the holes of the earth, from before the terror of Jehovah, and from the glory of his majesty, when he shall arise to terrify the earth.

to go into the clefts of the rocks, and into the fissures of the cliffs, from before the terror of Jehovah, and from the glory of his majesty, when he shall arise to terrify the earth.

and they shall come and settle all of them in the desolate valleys, and in the holes of the rocks, and on all thorn-bushes, and on all the pastures.

he shall dwell on high, the fortresses of the rocks shall be his high retreat; bread shall be given him, his water shall be sure.

inflaming yourselves with idols under every green tree, slaying the children in the valleys under the clefts of the rocks?
