“"I go hence like a shadow that declines" [Psalm 109:22]. By this he signified death itself. For as night comes of the shadow's declining, so death comes of mortal flesh. "And am driven away as the locusts." This I think would be more suitably understood of His members, that is, of His faithful disciples. That he might make it much plainer, he preferred writing "locusts" in the plural number: although many may be understood where the singular number is used, as in that passage, "He spoke, and the locust came;" but it would have been more obscure. His disciples, then, were driven away, that is, were put to flight by persecutors, either the multitude of whom He wished to be signified by the word locusts, or their passing from one place to another.”

“"I am poor and needy," and I am better only when in sorrow of heart I detest myself and seek your mercy, until what is faulty in me is repaired and made whole and finally I come to that state of peace that the eye of the proud cannot see. Yet in what others say about us and in what they know of our deeds there is grave danger of temptation. For our love of praise leads us to court the good opinion of others and hoard it for our personal glorification. And even when I reproach myself for it, the love of praise tempts me. There is temptation in the very process of self-reproach, for often, by priding himself in his contempt for vainglory, a person is guilty of even emptier pride; and for this reason his contempt of vainglory is an empty boast, because he cannot really hold it in contempt as long as he prides himself on doing so.”

“I am gone like the shadow when it declineth,.... When the sun is setting, and the shadow is going off; man's life is often compared to a shadow, because fleeting, momentary, and soon gone, Ch1 29:15 and death is expressed by going the way of all flesh; and by going to the grave, the house for all living, a man's long home, Jos 23:14 and so is the death of Christ, Luk 22:22, it may be rendered, "I am made to go" (h), denoting the violent death of Christ, who was cut off out of the land of the living, and whose life was taken away from the earth, Isa 53:8. I am tossed up and down as the locust; or "shaken out" (i) by the wind, as the locust is by the east wind, and carried from place to place, Exo 10:13, or when a swarm of them by a strong wind are crowded together and thrown upon one another; or like the grasshopper, which leaps from hedge to hedge, and has no certain abode: and such was the case of Christ here on earth; and especially it may have respect not only to his being sometimes in Judea and sometimes in Galilee, sometimes in the temple and sometimes in the mount of Olives; but to his being tossed about after his apprehension, when he was led to Annas, and then to Caiaphas, then to Pilate, then to Herod, then delivered to the soldiers, and by them led to Calvary, and crucified. (h) "cogor abire", Junius & Tremellius, Piscator, Cocceius; "abire factus sum", Gejerus, Michaelis. (i) "excussus sum", Montanus, Vatablus Gejerus, Michaelis; "excutior", Tigurine version, Musculus, Cocceius.”
