Cyril of Alexandria : In the first place it must be said that, even though there are some famous characters who are discovered to be guilty of acting in a not entirely honest way, however, since God in the holy Scriptures produces through them something useful for our salvation, let us drive away from us what may offend. If we take good care of our wisdom and intelligence, we are not unaware of what regards our profit. Let us consider how the blessed prophet Hosea took a prostitute as his wife, nor [did he refuse] a notorious marriage and was called the father of hateful sons, whose names were "Not my people" and "Unpitied." I will not hesitate to declare what this means. In fact, after those who were the nobles and the princes in Israel opposed the preaching of the prophets and the divine word was unpleasing to them, in the meantime God acted through his saints so that they might see the future from what was happening as if it was magnificently and expressly depicted in a picture. God did this so they might rededicate their minds to understanding their hope and might look with the strongest application for what would have been salutary to them and might also persuade others to do the same. And they learned that they would not have been the elected people anymore but would have been received among those who show no mercy, if they behaved with hardness and immoderation. Were not they afflicted by evils and overwhelmed by them everywhere?… Since we now understand the criterion and direction of the divine plan in those times, we will not condemn anymore the adultery of Tamar and Judah, but rather we will say that their union occurred in the divine plan. In fact, the former was in need of the seed of procreation as her legitimate husband was lacking it. The latter was guilty of a slight fault since he was free after his first wife had already died. So this union and generation teach us about our spiritual union and the rebirth of our mind. The human mind cannot be drawn to truth in a more appropriate way. — GLAPHYRA ON GENESIS, 6.2 Ephrem the Syrian : He then said, "She is more innocent than I," that is, "She is more righteous than I. What great sinners my sons were. 'Because of this, I did not give her to my son Shelah.' She is innocent of that evil suspicion that I held against her and [for which] I withheld my son Shelah from her." She who had been cheated out of marriage was justified in her fornication, and he who sent her out on account of his first two sons brought her back for the sake of his last two sons. "He did not lie with her again" because she had been the wife of his first two sons; nor did he take another wife, for she was the mother of his last two sons. — COMMENTARY ON Genesis 34:6 Jerome : (Verse 26.) But Judas acknowledged and said: she is more righteous than I, because I did not give her to my son Selom. In Hebrew, it says, she has been justified by me: not that she was just, but that in comparison to her, I have done less evil, not seeking base immorality, but seeking children. — Hebrew Questions on Genesis John Chrysostom : What is the meaning of "She has more right on her side than I"? In other words, she is guiltless, whereas I condemn myself and without anyone to accuse me I confess—or rather, I have sufficient accuser in the pledge given by me. Then Judah goes on to supply a defense for Tamar by saying, "because I did not give her to my son Shelah." Perhaps, however, this happened for the reason that I am about to give. I mean, Judah thought that it was through her fault that death fell on Er and Onan. For fear of this he did not give Shelah to her despite promising to do so. Accordingly, so as to prove in fact that she was not responsible for their death but rather that they were punished for their own wickedness ("God took his life" the text says, remember, and again, "he put him to death," in reference to the second one), Judah himself had intercourse with his own daughter-in-law all unawares. He learned by later developments that, far from it being her fault, those men's wickedness made them liable to suffer punishment. So Judah admitted his own sin, delivered her from punishment and, the text says, "had no further relations with her," showing that he would not previously have had intercourse with her if he had not done so in ignorance. — HOMILIES ON Genesis 62.7
