Judas Iscariot
Judas Iscariot (died AD) was a disciple and one of the original Twelve Disciples of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him and addressing him as "Rabbi" to reveal his identity to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. Judas's epithet "Iscariot" most likely means he came from the village of Kerioth, but this explanation is not universally accepted and many other possibilities have been suggested.
Judaism's view of Jesus
Maimonides lamented the pains that Jews felt as a result of new faiths that attempted to supplant Judaism, specifically Christianity and Islam. Referring to Jesus, he wrote:
Even Jesus the Nazarene who imagined that he would be Messiah and was killed by the court, was interpreted as prophesied by Daniel. So that it was said, "And the members of the outlaws of your nation would be carried to make a (prophetic) vision stand. And they stumbled" (Daniel 11.14). Because, is there a greater stumbling-block than this one? So that all of the prophets spoke that the Messiah redeems Israel, and saves them, and gathers their banished ones, and strengthens their commandments. And this one caused (nations) to destroy Israel by sword, and to scatter their remnant, and to humiliate them, and to exchange the Torah, and to make the majority of the world err to serve a divinity besides God.
