'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,

Thy terribleness hath deceived thee, and the pride of thine heart, O thou that dwellest in the clefts of the rock, that holdest the height of the hill: though thou shouldest make thy nest as high as the eagle, I will bring thee down from thence, saith the LORD.
