'Clefts of the Rock' in the Bible

These [armies, like flies and bees] will all come and settle on the steep and rugged ravines and in the clefts of the rocks, and on all the thorn bushes and in all the watering places.

Who inflame yourselves [with lust in pagan rites] among the oaks (terebinth trees),Under every green and leafy tree,Who slaughter the children [in sacrifice] in the ravinesUnder the clefts of the rocks?

“Behold (listen carefully), I will send for many fishermen,” says the Lord, “and they will fish for them; and afterward I will send for many hunters, and they will hunt them from every mountain and from every hill and out of the clefts of the rocks.

“As for Your terror,The pride and arrogance of your heart have deceived you,O you who live in the clefts of the rock (Sela also called Petra),Who hold and occupy the height of the hill.Though you make your nest as high as the eagle’s,I will bring you down from there,” says the Lord.
