" (a) To the chief Musician, Altaschith, Michtam of David, when he fled from Saul in the cave." Be merciful unto me, O God, be merciful unto me: for my soul trusteth in thee: yea, in the shadow of thy wings will I make my refuge, until [these] (a) calamities be overpast.
(a) This was either the beginning of a certain song, or the words which David uttered when he stayed his affection.
(b) He compares the afflictions which God lays on his children, to a storm that comes and goes.
