Ps 17:1-15. This Psalm is termed a prayer because the language of petition is predominant. With a just cause, sincerely presented, the writer prays for a just decision and help and protection. Pleading former mercies as a ground of hope, he urges his prayer in view of the malice, pride, rapacity, and selfishness of his foes, whose character is contrasted with his pious devotion and delight in God's favor.

13-15. disappoint—literally, "come before," or, "encounter him." Supply "with" before "sword" (Ps 17:13), and "hand" (Ps 17:14). These denote God's power.

14. men … world—all men of this present time. They appear, by fulness of bread and large families, to be prosperous; but (Ps 17:15) he implies this will be transient, contrasting his better portion in a joyful union with God hereafter.
