 :Here is the full quote from the page: "The personal existence of Jesus as Jehoshua Ben-Pandira can be established beyond a doubt. One account affirms that, according to a genuine Jewish tradition 'that man (who is not to be named) was a disciple of Jehoshua Ben-Perachia.' It also says, 'He was born in the fourth year of the reign of the Jewish King Alexander Jannæus, notwithstanding the assertions of his followers that he was born in the reign of Herod.'  That would be more than a century earlier than the date of birth assigned to the Jesus of the Gospels! But it can be further shown that Jehoshua Ben-Pandira may have been born considerably earlier even than the year 102 BC, although the point is not of much consequence here. Jehoshua, son of Perachia, was a president of the Sanhedrin — the fifth, reckoning from Ezra as the first: one of those who in the line of descent received and transmitted the oral law, as it was said, direct from Sinai. There could not be two of that name. This Ben-Perachia had begun to teach as a Rabbi in the year 154 BC. We may therefore reckon that he was not born later than 180-170 BC, and that it could hardly be later than 100 BC when he went down into Egypt with his pupil. For it is related that he fled there in consequence of a persecution of the Rabbis, feasibly conjectured to refer to the civil war in which the Pharisees revolted against King Alexander Jannæus, and consequently about 105 BC If we put the age of his pupil, Jehoshua Ben-Pandira, at fifteen years, that will give us an approximate date, extracted without pressure, which shows that Jehoshua Ben-Pandira may have been born about the year 120 BC."
