Charles H. Spurgeon on Psalms 52:1

O mighty man. These words may be added by way of irony, as if he had said, A great deal of valour and prowess you have shown in slaying a company of unarmed men, the priests of the Lord, yea, women and children, no way able to resist you or else to imply the ground of his vain boasting, to wit, either his present greatness, as being a man in great place, and of great power with Saul; or the great preferments he expected from Saul. Arthur Jackson.
