Charles H. Spurgeon on Psalms 109:29

Let mine adversaries be clothed with shame. It is a prophecy as well as a wish, and may be read both in the indicative and the imperative. Where sin is the underclothing, shame will soon be the outer vesture. He who would clothe good men with contempt shall himself be clothed with dishonour. And let them cover themselves with their own confusion, as with a mantle. Let their confusion be broad enough to wrap them all over from head to foot, let them bind it about them and hide themselves in it, as being utterly afraid to be seen. Now they walk abroad unblushingly and reveal their own wickedness, acting as if they either had nothing to conceal or did not care whether it was seen or no; but they will be of another mind when the great Judge deals with them, then will they entreat mountains to hide them and hills to fall upon them, that they may not be seen: but all in vain, they must be dragged to the bar with no other covering but their own confusion.
