Caesarius of Arles : Upon seeing Joseph, his brothers discussed his death; just as when the Jews saw the true Joseph, Christ the Lord, they all resolved with one plan to crucify him. His brothers robbed Joseph of his outside coat that was of divers colors; the Jews stripped Christ of his bodily tunic at his death on the cross. When Joseph was deprived of his tunic he was thrown into a cistern, that is, into a pit; after Christ was despoiled of human flesh, he descended into hell. Afterward Joseph is lifted up out of the cistern and is sold to the Ishmaelites, that is, to the Gentiles; when Christ returns from hell, he is bought by all nations at the price of faith. Upon the advice of Judah, Joseph is sold for thirty pieces of silver; Christ is sold for the same amount upon the counsel of Judas Iscariot. Now in different translations Joseph is not written as sold at the same price, for some say it was twenty pieces of silver and others thirty. This spiritually signifies that Christ was not to be believed and loved equally by all people. In fact, even in the church some love him more, others less, for Christ means more to the soul that loves him with greater charity. Joseph went down to Egypt; Christ went into the world. Joseph saves Egypt from want of grain; Christ frees the world from a famine of the Word of God. — SERMON 89.2 Chromatius of Aquileia : Let us observe a great mystery: for Joseph twenty pieces of gold were given, for the Lord thirty pieces of silver. The servant was sold at a higher price than the Master. To be sure people are wrong in fixing the price of the Lord, because the One who is sold is beyond human evaluation. Let us consider this mystery with more attention. For the Lord the Jews offered thirty pieces of silver; for Joseph the Ishmaelites offered twenty pieces of gold. The Ishmaelites bought the servant at a higher price than that paid by the Jews for the Master. The first worshiped in Joseph the image of Christ; the latter only had contempt for the reality itself that was in Christ. Therefore the Jews offered a lower price for Christ, because they estimated the passion of the Lord to be cheap. But how is it possible to estimate the passion of the Lord to be cheap, when it is the price for the redemption of the entire world? Listen to the apostle, who demonstrates that to us by saying, "You were bought at a high price." And listen to the apostle Peter, who says in a similar manner, "You were ransomed from your futile ways not with perishable things like silver and gold but with the precious blood of the immaculate Son of God." If we were bought back from death with gold or silver, our ransom would have been cheap, because humanity is more precious than gold and silver; but in truth we are ransomed at an invaluable price, because the one who ransomed us through his passion is invaluable. — SERMON 24.4 Jerome : (Verse 28) And the Ishmaelites sold Joseph for twenty silver coins. In Hebrew, silver coins are used instead of gold coins. For the Lord should not be sold for a lesser metal than Joseph. — Hebrew Questions on Genesis John Chrysostom : What an unlawful contract! What baleful profit! What illicit sale! The one who caused the same birth pangs as yourselves, the one so dear to your father, the one who came to see you, who never did you the slightest wrong, you endeavored to sell—and sell to savage people traveling down to Egypt.What unlawful frenzy! What dreadful malice! I mean, even if you did this out of fear of the dreams, convinced that they would certainly come to pass in every detail, why did you attempt the impossible and give evidence by what you did of your hostility toward God, who had foretold this to Joseph? If, on the contrary, you give no credence to the dreams but consider them nonsense, why did you do what brought you everlasting defilement and caused your father irreparable grief? But what excess of passion—or rather, of a bloodthirsty intention! You see, when someone is obsessed with some improper exploit and becomes intoxicated with improper designs, he does not keep before him the unsleeping eye; he has no respect even for nature or anything else that could bring him to compassion. That was the situation with these men too. They were not concerned that he was their brother, that he was only a youth, that he was so dear to their father, that he had no experience of life in foreign parts or living in exile and yet was on the point of departing for such a land and living among savages. Instead, they abandoned every sane consideration and had one thing on their minds, allowing their envy to have (as they thought) an immediate effect. — HOMILIES ON Genesis 61.15-16 Augustine of Hippo : THE MIDIANITES NAMED ISHMAELITES. — It is known that Ishmael was the son of Abraham through Hagar, while the Midianites were through Keturah. Should one think perhaps that they formed a single people, since Scripture had said that Abraham had given gifts to the children of his concubines, i.e. Hagar and Keturah, and had dismissed them with his son Isaac, sending them to the eastern region (Cf. Gen. 25:6)? [ — QUESTIONS ON GENESIS, Q. 123 (tr. J. Litteral, draft)
