'Clefts' in the Bible

“I am about to send for many fishermen”—this is the Lord’s declaration—“and they will fish for them. Then I will send for many hunters, and they will hunt them down on every mountain and hill and out of the clefts of the rocks,

As to the terror you cause,your presumptuous heart has deceived you.You who live in the clefts of the rock,you who occupy the mountain summit,though you elevate your nest like the eagle,even from there I will bring you down.This is the Lord’s declaration.
