'Clefts' in the Bible

to enter into the crevices of the rocks and into the clefts of the crags from the presence of the terror of Yahweh and from the glory of his majesty, {when he rises} to terrify the earth.

And all of them will come and settle in the rivers of the cliffs and in the clefts of the rocks and on all of the thornbushes and watering places.

who burn with lust among the oaks, under every leafy tree, who slaughter children in the valleys, under the clefts of the rocks?
