EXPOSITION
This psalm—the "twin psalm" with the last—has also an elaborate "title," which runs thus: "To the precentor (or chief musician): destroy not; David's; Michtam; when he fled from Saul; in the cave." The meaning of the second and fourth headings is doubtful Some explain the second as "musical;" others as an allusion to David's words when he bade Abishai not to kill Saul. The last two clauses give the place and occasion of the composition. It was written "in the cave"—probably the cave of Adullam (1 Samuel 22:1)—when David was flying from Saul. No valid reason can be urged against these statements.
The psalm is divided by its refrain (Psalms 57:5, Psalms 57:11) into two parts, which are further subdivided by the pause mark, "Selah." The initial strophe (Psalms 57:1-5) is a mixture of prayer and complaint; the concluding one (Psalms 57:6-11) begins with complaint (Psalms 57:6), but almost immediately changes into "a strain of exulting and triumphant confidence," so exulting and triumphant as to cause its selection by our Church for recitation on Easter Day.
