Let mine adversaries be clothed with shame; rather, my adversaries shall be clothed with shame. "The prayer is now, in conclusion, changed into a confident expectation" (Dean Johnson). And let them (rather, and shall) cover themselves with their own confusion, as with a mantle (comp. Psalms 109:18). Instead of the "cursing" with which the wicked delighted to clothe themselves, they shall be forced to wear a covering of shame and confusion of face.
The psalm terminates with a short burst of praise, the writer feeling assured that his prayer is granted, and that he will shortly triumph over his enemies.
