In my The Death of the Messiah, preparatory to examining the Gospel accounts of the trial/interrogation of Jesus by the chief priest(s) and San-hedrin, I surveyed the extra-Gospel evidence for authoritative Jewish involvement in the death of Jesus, derived from Jewish, Christian, and pagan sources. From the Jewish evidence I discussed two items: the witness of Josephus (Ant. 18.3.3; #63–t) and a baraita from TalBab Sanhedrin 43a which I quoted from the London Soncino translation (Nezikin volume 3.281):

On the eve of Passover Yeshu was hanged. For forty days before the execution took place, a herald went forth and cried, ‘He is going forth to be stoned because he has practised sorcery and enticed Israel to apostacy. Anyone who can say anything in his favour, let him come forward and plead on his behalf.’ But since nothing was brought forward in his favour he was hanged on the eve of Passover.
