Let mine adversaries be clothed with shame - Let confusion and disappointment seem to cover them, so as to constitute a garment. See the notes at Psalms 109:18-19. They had “clothed themselves with cursing” Psalms 109:18, and the prayer now is, that the covering of shame might be as complete and entire.
And let them cover themselves with their own confusion as with a mantle - As with an outer garment - the mantle or robe - which they might wrap all round them. Let it be so abundant that they may entirely wrap their person in it. Let their confusion correspond with their sin in the fullest manner.
