'Cave' in the Bible

To the Overseer. -- 'Destroy not.' -- A secret treasure of David, in his fleeing from the face of Saul into a cave. Favour me, O God, favour me, For in Thee is my soul trusting, And in the shadow of Thy wings I trust, Until the calamities pass over.

An Instruction of David, a Prayer when he is in the cave. My voice is unto Jehovah, I cry, My voice is unto Jehovah, I entreat grace.
