'Cave' in the Bible

{To the chief Musician. 'Destroy not.' Of David. Michtam; when he fled from Saul in the cave.} Be gracious unto me, O God, be gracious unto me; for my soul taketh refuge in thee: yea, in the shadow of thy wings do I take refuge, until the calamities be overpast.

{An instruction of David; when he was in the cave: a prayer.} I cry unto Jehovah with my voice: with my voice unto Jehovah do I make supplication.
