Matthew's genealogy differs from Luke's, but also why Matthew counts fourteen generations rather than thirteen. Blair sees the various extant versions as the predictable result of copyists repeatedly attempting to correct an apparent mistake. Others, including Victor Paul Wierwille, argue that here the Aramaic original of Matthew used the word gowra (which could mean father), which, in the absence of vowel markings, was read by the Greek translator as gura (husband). In any case, an early understanding that Matthew traced Mary's genealogy would explain why the contradiction between Matthew and Luke apparently escaped notice until the 3rd century. Lukan version of Levirate marriage theory Although most accounts ascribing the Luke genealogy to Mary's line do not include a levirate marriage this is added by the above sources. Each of these texts then goes on to describe, just as in Julius Africanus (but omitting the name of Estha), how Melchi was related to Joseph through a levirate marriage. Bede assumed that Julius Africanus was mistaken and corrected Melchi to Matthat. Since papponymics were common in this period, however, it would not be surprising if Matthat were also named Melchi after his grandfather. Panther Controversy has surrounded the name Panther, mentioned above, because of a charge that Jesus' father was a soldier named Pantera. Celsus mentions this in his writing, The True Word, where he is quoted by Origen in Book 1:32. "But let us now return to where the Jew is introduced, speaking of the mother of Jesus, and saying that "when she was pregnant she was turned out of doors by the carpenter to whom she had been betrothed, as having been guilty of adultery, and that she bore a child to a certain soldier named Panthera." Epiphanius, in refutation of Celsus, writes that Joseph and Cleopas were sons of "Jacob, surnamed Panther." Two Talmudic-era texts referring to a "Jesus, son of Pantera (Pandera)" are Tosefta Hullin 2:22f: "Jacob… came to heal him in the name of Jesus son of Pantera" and Qohelet Rabbah 1:8(3): "Jacob… came to heal him in the name of Jesus son of Pandera" and some editions of the Jerusalem Talmud also specifically name Jesus as the son of Pandera: Jerusalem Abodah Zarah 2:2/7: "someone… whispered to him in the name of Jesus son of Pandera"; Jerusalem Shabboth 14:4/8: "someone… whispered to him in the name of Jesus son of Pandera"; Jerusalem Abodah Zarah 2:2/12: "Jacob…
