Jesus in the Talmud - Wikipedia
According to the link above, the Talmud says:
On (Sabbath eve and) the eve of Passover, Jesus the Nazarene was hanged and a herald went forth before him forty days heralding,
"Jesus the Nazarene is going forth to be stoned because he practiced sorcery and instigated and seduced Israel to idolatry. Whoever knows anything in defense may come and state it." But since they did not find anything in his defense they hanged him on (Sabbath eve and) the eve of Passover. Ulla said:
"Do you suppose that Jesus the Nazarene was one for whom a defense could be made? He was a mesit (someone who instigated Israel to idolatry), concerning whom the Merciful [God] says: Show him no compassion and do not shield him (Deut. 13:9)
