They hanged Yeshua of Nazareth on the Sabbath of the Passover. But for forty days before, a herald went in front of him crying, "Yeshua of Nazareth is to be stoned because he practiced sorcery and seduced Israel and lead them away from God. Anyone who can provide evidence on his behalf should come forward to defend him." When, however, nothing favorable about him was found, he was hanged on the Sabbath of the Passover. (Sanhedrin 43a)
Also, in 1972, Professor Schlomo Pines of the Hebrew University in Jerusalem announced his discovery of a manuscript of Josephus's writings in the tenth-century Melkite historian Agapius. This is important because it has long been known that the Greek version of his passage about Jesus was tampered with by Christians. This version was in Arabic and historians have said it reflects the original version, which reads as follows at Antiquities 18:63:
At this time there was a wise man called Jesus, and his conduct was good, and he was known to be virtuous. Many people among the Jews and the other nations became his disciples. Pilate condemned him to be crucified and to die. But those who had become his disciples did not abandon his discipleship. They reported that he had appeared to them three days after his crucifixion and that he was alive. Accordingly, he was perhaps the Messiah, concerning whom the prophets have reported wonders. And the tribe of the Christians, so named after him, has not disappeared to this day.
When non Christians, in fact Jews, some of whom were enemies of early Christianity, admit to many of the facts recorded in the Gospel accounts, this is a powerful extra-biblical witness to the Gospels and their authenticity as historical documents.
