'Crags' in the Bible

Who inflame yourselves among the oaks,Under every luxuriant tree,Who slaughter the children in the ravines,Under the clefts of the crags?

“Leave the cities and dwell among the crags,O inhabitants of Moab,And be like a dove that nestsBeyond the mouth of the chasm.

“Behold, I am against you, O destroying mountain,Who destroys the whole earth,” declares the Lord,“And I will stretch out My hand against you,And roll you down from the crags,And I will make you a burnt out mountain.
