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.
Jewish deicide
If so, the author would be the first writer in the Lukan-Pauline tradition to raise unambiguously the accusation of deicide against Jews. This text blames the Jews for allowing King Herod and Caiaphas to execute Jesus, despite their calling as God's people (i.e., both were Jewish). It says "you did not know, O Israel, that this one was the firstborn of God". The author does not attribute particular blame to Pontius Pilate, but only mentions that Pilate washed his hands of guilt.
