Psalms 55:5

"Fearfulness and trembling have come upon me, and darkness hath covered me." "And I have said," "He that hateth his brother, is in darkness until now." If love is light, hatred is darkness. And what saith to himself one set in that weakness and troubled in that exercise? "Who shall give me wings as to a dove, and I shall fly and shall rest?" Either for death he was wishing, or for solitude he was longing. So long, he saith, as this is the work with me, as this command is given me, that I should love enemies, the revilings of these men, increasing and shadowing me, do derange mine eye, perturb my sight, penetrate my heart, slay my soul. I could wish to depart, but weak I am, lest by abiding I should add sins to sins: or at least may I be separated for a little space from mankind, lest my wound suffer from frequent blows, in order that when it hath been made whole it may be brought back to the exercise. This is what takes place, brethren, and there ariseth ofttimes in the mind of the servant of God a longing for solitude, for no other reason than because of the multitude of tribulations and scandals, and he saith, "Who shall give me wings?" Doth he find himself without wings, or rather with bound wings? If they are wanting, be they given; if bound, be they loosed; because even he that looseth a bird's wings, either giveth, or giveth back to it its wings. For it had not as though its own them, wherewith it could not fly. Bound wings make a burden. "Who," he saith, "shall give me wings as to a dove, and I shall fly and shall rest?" Shall rest, where? I have said there are two senses here: either, as saith the Apostle, "To be dissolved and to be with Christ, for it is by far the best thing." ...Even he that amended cannot be, is thine, either by the fellowship of the human race, or ofttimes by Church Communion; he is within, what wilt thou do? whither wilt go? […]

We would falter when the persecutor is present if the comforter were absent. And because the strength to endure or some relief from life's burdens for necessary ministry did not come from themselves, see what he said: "I make known to you, brothers, the affliction that came upon us in Asia, that we were burdened exceedingly, beyond our strength." That affliction surpassed human strength: did it also surpass divine help? He said, "We were burdened beyond measure, beyond our strength." How much beyond strength? See that he speaks of the strength of the soul: "So that we despaired even of life." How burdened was the Apostle by the multitude of oppressions that he, whom love urged to live, was wearied of life! How love impelled him to live, that love of which he says elsewhere: "But to remain in the flesh is necessary for your sakes." Behold, such a great persecution had increased, and such a tribulation, that he despaired even of life. Behold, fear and trembling came upon him, and darkness covered him, as you heard when it was said in the Psalm. For it is the voice of the body of Christ, the voice of the members of Christ. Do you wish to recognize your own voice there? Be a member of Christ. "Fear," he says, "and trembling fell upon me, and darkness covered me. And I said: Who will give me wings like a dove? And I will fly and be at rest." Does it not seem that the Apostle said this when he said: "So that we despaired even of life"? He somehow suffered weariness from the snare of the flesh; he wished to fly to Christ; the abundance of tribulations beset his path but did not block it. He was weary of life, but not in that eternal life, of which he says: "For to me, to live is Christ, and to die is gain." But since he was held here by love, what follows? "But if to live in the flesh means fruitful labor for me, then I do not know which I prefer. […]

"My heart was troubled." Here the magnitude of the tribulation is set forth with respect to three things: that it is close at hand, great, and efficacious. When someone wishes to exaggerate his pain, he says he has been struck to the heart. And therefore …

When without are fightings no marvel that within are fears; and, if it was upon the occasion of Absalom's rebellion, we may suppose that the remembrance of his sin in the matter of Uriah, which God was now reckoning with him for, added as much more to the fright.

Fearfulness and trembling are come upon me,....
