John Trapp Complete Commentary
Psalms 57:1
Psalms 57:1 «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] calamities be overpast.
Al-taschith] i.e. Destroy not; μη διαφθειρης (Sept.). David being in imminent danger of destruction in the cave, might send up this short request as it were in a fright, before he uttered this ensuing prayer. Al-taschith in such an exigent might well be an effectual prayer; as was the woman of Canaan's Lord, help me, and the sick man's Abba, Father; or these might now be his words (to Abishai, or some other of his servants, whose fingers even itched to be doing with Saul), as afterwards they were upon a like occasion, 1 Samuel 26:9. Destroy not Saul. See thou do it not.
Michtam of David] See Psalms 16:1, title.
When he fled from Saul in the cave] 1 Samuel 24:1, or, into the cave for shelter; and where, when he might have cut Saul's throat, he cut his coat only, and was inwardly checked for it; nevertheless the Spirit came upon him, which was no small comfort, as Aben Ezra here observeth, and he said,
Ver. 1. Be merciful unto me, O God, be merciful] q.d. Now or never help at a dead lift. Bis, pro more rogantium, ad corroborandum, saith Kimchi. Other Jewish doctors give this reason of the repetition of his petition: "Be merciful," &c., lest either I fall into Saul's hands, or Saul into mine; lest desire for revenge prick me on to kill him. Or, have mercy on me, that I sin not; or if I do sin, that I may repent (Midr. Tillin.)
For my soul trusteth in thee] An excellent argument, so it comes from the soul, so it be heart-sprung.
Yea, in the shadow of thy wings, &c.] As the little chicken in danger of the kite hovereth, and covereth under the hen.
Until these calamities be over past] For long they will not continue. Nubecula est, cito transibit, said Athanasius of the Arian persecutions, which for present were very sharp. So Master Jewel, about the beginning of Queen Mary's reign, persuading many to patience, said often, Haec non durabunt setatem, This sharp shower will soon be over.
