'Rocks' in the Bible

And men will go into cracks of the rocks, and into holes of the earth, for fear of the Lord, and before the glory of his power, when he comes out of his place, shaking the earth with his strength.

To take cover in the cracks of the rocks, and in the holes of the hills, for fear of the Lord, and before the glory of his power, when he comes out of his place, shaking the earth with his strength.

And they will come, covering all the waste valleys, and the holes of the rocks, and the thorns, and all the watering-places.

He will have a place on high: he will be safely shut in by the high rocks: his bread will be given to him; his waters will be certain.

You who are burning with evil desire among the oaks, under every green tree; putting children to death in the valleys, under the cracks of the rocks?
