'Cliffs' in the Bible

When the men of Israel saw that they were in a strait (for the people were hard-pressed), then the people hid themselves in caves, in thickets, in cliffs, in cellars, and in pits.

The high mountains are for the wild goats;The cliffs are a refuge for the shephanim.

In order to go into the caverns of the rocks and the clefts of the cliffsBefore the terror of the Lord and the splendor of His majesty,When He arises to make the earth tremble.

They will all come and settle on the steep ravines, on the ledges of the cliffs, on all the thorn bushes and on all the watering places.
