The Tzoah Rotachat in the Talmud and the Zohar is a location in Gehenna where the souls of Jews who committed certain sins are sent for punishment.
"Our rabbinic texts, all in the Bavli, emphasize that Jesus, the new Balaam, does not have a portion in the world to come: his fate is that he must be punished in hell forever, with no chance of redemption—and the same is true for his followers: they better give up any hope of earning eternal life in his succession, as his apostles promise."
"Jesus is accordingly, in the following curious Talmudic legend, thought to sojourn in hell A certain Onkelos b Kalonikos, son of Titus sister, desired to embrace Judaism, and called up from hell by magic first Titus, then Balaam, and finally Jesus, who are here taken together as the worst enemies of Judaism Onkelos then asked the nature of his punishment, and was told that it was the degrading fate of those who mock the wise (Git 56b–57a)"
