'Clefts' in the Bible

My dove, in the clefts of the rock, In the covert of the precipice, Let me see thy countenance, let me hear thy voice; For sweet is thy voice, and thy countenance is comely.

to go into the clefts of the rocks, and into the fissures of the cliffs, from before the terror of Jehovah, and from the glory of his majesty, when he shall arise to terrify the earth.

inflaming yourselves with idols under every green tree, slaying the children in the valleys under the clefts of the rocks?

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

For behold, Jehovah commandeth, and he will smite the great house with breaches, and the little house with clefts.

The pride of thy heart hath deceived thee, thou that dwellest in the clefts of the rock, whose habitation is high; he that saith in his heart, Who shall bring me down to the ground?
