There were, then, among the Jews certain men who were prophets of God, through whom the prophetic Spirit published beforehand things that were to come to pass, ere ever they happened. And their prophecies, as they were spoken and when they were uttered, the kings who happened to be reigning among the Jews at the several times carefully preserved in their possession, when they had been arranged in books by the prophets themselves in their own Hebrew language. And when Ptolemy king of Egypt formed a library, and endeavoured to collect the writings of all men, he heard also of these prophets, and sent to Herod, who was at that time king of the Jews, 1826 requesting that the books of the prophets be sent to him. And Herod the king did indeed send them, written, as they were, in the foresaid Hebrew language. And when their contents were found to be unintelligible to the Egyptians, he again sent and requested that men be commissioned to translate them into the Greek language. And when this was done, the books remained with the Egyptians, where they are until now. They are also in the possession of all Jews throughout the world; but they, though they read, do not understand what is said, but count us foes and enemies; and, like yourselves, they kill and punish us whenever they have the power, as you can well believe. For in the Jewish war which lately raged, Barchochebas, the leader of the revolt of the Jews, gave orders that Christians alone should be led to cruel punishments, unless they would deny Jesus Christ and utter blasphemy. In these books, then, of the prophets we found Jesus our Christ foretold as coming, born of a virgin, growing up to man’s estate, and healing every disease and every sickness, and raising the dead, and being hated, and unrecognised, and crucified, and dying, and rising again, and ascending into heaven, and being, and being called, the Son of God. We find it also predicted that certain persons should be sent by Him into every nation to publish these things, and that rather among the Gentiles [than among the Jews] men should believe on Him. And He was predicted before He appeared, first 5000 years before, and again 3000, then 2000, then 1000, and yet again 800; for in the succession of generations prophets after prophets arose.
Some attribute this blunder in chronology to Justin, others to his transcribers: it was Eleazer the high priest to whom Ptolemy applied.
