Ashamed and sore vexed - May they as deeply deplore their transgressions as I have done mine! May they return; may they be suddenly converted! The original will bear this meaning, and it is the most congenial to Christian principles.
Let all mine enemies be ashamed - Be so brought to see their folly that they shall be ashamed of their conduct. The wish is that they might be brought to see their own guilt - a wish certainly which it is right to cherish in regard to all evil-doers.
And sore vexed - Compare the notes at Psalm 5:10. The same Hebrew word is used here which occurs in Psalm 6:2-3, and rendered “vexed.” It is a word which denotes trouble, trembling, consternation; and the meaning here is, that the psalmist prayed that they might be confounded or disconcerted in their plans - a prayer which is certainly proper in regard to all the purposes of the wicked. No one should desire that the purposes of the wicked should prosper; and not to desire this is to desire that they may be foiled and overcome in their schemes. This must be the wish of every good man.
Let them return - Turn back, or be turned back; that is, let them be repulsed, and compelled to turn back from their present object.
And be ashamed suddenly - Hebrew, “In a moment;” instantaneously. He desired that there might be no delay, but that their defeat might be accomplished at once. As it was right to pray that this might occur, so it was right to pray that it might occur without delay, or as speedily as possible. The sooner the plans of sinners are confounded, the better.
