'Clefts' in the Bible

“Behold, I am going to send for many fishermen,” declares the Lord, “and they will fish for them; and afterwards I will send for many hunters, and they will hunt them from every mountain and every hill and from the clefts of the rocks.

“As for the terror of you,The arrogance of your heart has deceived you,O you who live in the clefts of the rock,Who occupy the height of the hill.Though you make your nest as high as an eagle’s,I will bring you down from there,” declares the Lord.
