"To the chief Musician upon Jonathelemrechokim, Michtam of David, (a) when the Philistines took him in Gath." Be merciful unto me, O God: for (b) man would swallow me up; he fighting daily oppresseth me.
(a) Being chased by the fury of his enemies into a strange country, he was a dumb dove not seeking vengeance.
(b) He shows that if God will help him, it must be now or never for all the world is against him and ready to devour him.
