2 What is, “Thou that feedest Israel, hearken, You that conducts Joseph like sheep”?. He is being invoked to come, He is being expected until He come, He is being yearned for until He come. Therefore may He find “men guiding:” “You that conducts,” he says, “Joseph like sheep:” Joseph himself like sheep. Joseph himself are the sheep, and Joseph himself is a sheep. Observe Joseph; for although even the interpretation of his name does aid us much, for it signifies increase; and He came indeed in order that the grain given to death might arise manifold; that is, that the people of God might be increased....“You that sits upon the Cherubin.” Cherubin is the seat of the glory of God, and is interpreted the fullness of knowledge. There God sits in the fullness of knowledge. Though we understand the Cherubin to be the exalted powers and virtues of the heavens: yet, if you will, you will be Cherubin. For if Cherubin is the seat of God, hear what says the Scripture: “The soul of a just man is the seat of wisdom.” How, you say, shall I be the fullness of knowledge? Who shall fulfil this? You have the means of fulfilling it: “The fullness of the Law is love.” Do not run after many things, and strain yourself. The amplitude of the branches does terrify you: hold by the root, and of the greatness of the tree think not. Be there in you love, and the fullness of knowledge must needs follow. For what does he not know that knows love? Inasmuch as it has been said, “God is love.” “Appear.” For we went astray because You did not appear. “Before Ephraim and Benjamin and Manasse”. Appear, I say, before the nation of the Jews, before the people of Israel. For there is Ephraim, there Manasses, there Benjamin. But to the interpretation let us look: Ephraim is fruit-bearing, Benjamin son of right hand, Manasses one forgetful. Appear Thou then before one made fruitful, before a son of the right hand: appear Thou before one forgetful, in order that he may be no longer forgetful, but You may come into his mind that hast delivered him....For weak You were when it was being said, “If Son of God He is, let Him come down from the Cross.” You were seeming to have no power: the persecutor had power over You: and You showed this aforetime, for Jacob too himself prevailed in wrestling, a man with an angel. Would he at any time, except the angel had been willing? And man prevailed, and the angel was conquered: and victorious man holds the angel, and says, “I will not let you go, except you shall have blessed me.” A great sacrament! He both stands conquered, and blesses the conqueror. Conquered, because he willed it; in flesh weak, in majesty strong....Having been crucified of weakness, rise in power: “Stir up Your power, and come Thou, to save us.”
3. “O God, convert us.” For averse we have been from You, and unless You convert us, we shall not be converted. “And illumine Your face, and we shall be saved”. Hath He anywise a darkened face? He has not a darkened face, but He placed before it a cloud of flesh, and as it were a veil of weakness; and when He hung on the tree, He was not thought the Same as He was after to be acknowledged when He was sitting in Heaven. For thus it has come to pass. Christ present on the earth, and doing miracles, Asaph knew not; but when He had died, after that He rose again, and ascended into Heaven, he knew Him. He was pricked to the heart, and he may have spoken also of Him this testimony which now we acknowledge in this Psalm. You covered Your face, and we were sick: illumine Thou the same, and we shall be whole.
4. “O Lord God of virtues, how long will You be angry with the prayer of Your servant?”. Now Your servant. You were angry at the prayer of Your enemy, will You still be angry with the prayer of Your servant? You have converted us, we know You, and will You still be angry with the prayer of Your servant? You will evidently be angry, in fact, as a father correcting, not as a judge condemning. In such manner evidently You will be angry, because it has been written, “My son, drawing near unto the service of God, stand thou in righteousness and in fear, and prepare your soul for temptation.” Think not that now the wrath of God has passed away, because you have been converted. The wrath of God has passed away from you, but only so that it condemn not for everlasting. But He scourges, He spares not: because He scourges every son whom He receives. If you refuse to be scourged, why do you desire to be received? He scourges every son whom He receives. He who did not spare even His only Son, scourges every one. But nevertheless, “How long will You be angry with the prayer of Your servant?” No longer your enemy: but, “You will be angry with the prayer of Your servant,” how long? There follows: “You will feed us with the bread of tears, and wilt give us to drink with tears in measure”. What is, “in measure”? Hear the Apostle: “Faithful is God, who does not suffer you to be tempted above that you are able to bear.” The measure is, according to your powers: the measure is, that you be instructed, not that thou be crushed.
5. “You have set us for a contradiction to our neighbours”. Evidently this did come to pass: for out of Asaph were chosen they that should go to the Gentiles and preach Christ, and should have it said to them, “Who is this proclaimer of new demons?” “You have set us for a contradiction to our neighbours.” For they were preaching Him who was the subject of the contradiction. Whom did they preach? That after He was dead, Christ rose again. Who would hear this? Who would know this? It is a new thing. But signs did follow, and to an incredible thing miracles gave credibility. He was contradicted, but the contradictor was conquered, and from being a contradictor was made a believer. There, however, was a great flame: there the martyrs fed with the bread of tears, and given to drink in tears, but in measure, not more than they are able to bear; in order that after the measure of tears there should follow a crown of joys. “And our enemies have sneered at us.” And where are they that sneered? For a long while it was said, Who are they that worship the Dead One, that adore the Crucified? For a long while so it was said. Where is the nose of them that sneered? Now do not they that censure flee into caves, that they may not be seen? But ye see what follows: “O Lord God of virtues, convert us, and show Your face, and we shall be whole”. “A vineyard out of Egypt You have brought over, You have cast out the nations, and hast planted her”. It was done, we know. How many nations were cast out? Amorites, Cethites, Jebusites, Gergesites, and Evites: after whose expulsion and overthrow, there was led in the people delivered out of Egypt, into the land of promise. Whence the vineyard was cast out, and where she was planted, we have heard. Let us see what next was done, how she believed, how much she grew, what ground she covered.
