"For their blood demands vengeance. When the Holy One, blessed be He, comes to demand the blood of Rabbi Akiva, He will demand the blood of Bar Kappara. He has not forgotten the cry of the oppressed. He does not forget the blood of Israel from the nations, nor the blood of righteous ones who were killed.
They are Rabban Shimon ben Gamliel, Rabbi Yishmael ben Elisha, Rabbi Yishbab the Scribe, Rabbi Chutzpit the Translator, Rabbi Yosei, Rabbi Yehuda ben Bava, Rabbi Yehuda the Notary, Rabbi Shimon ben Azzai, Rabbi Chanina ben Teradion, and Rabbi Akiva. Regarding them, the verse speaks: "For their blood demands vengeance." And in the future, the Holy One, blessed be He, will demand the blood of Bar Kappara and Rabbi Yehuda the Notary.
Once, a wicked government decree was made to kill Rabbi Yehuda the Notary. What did Bar Kappara do? He made himself a judge and judged him. And when he came to give him a spoon to eat with, he decreed that another person should be slaughtered under him.
He then spread slanderous rumors that Rabbi Yehuda was not killed. The wicked government then issued another decree to kill them both, and they were both killed and cut into pieces. And in the future, the Holy One, blessed be He, will demand their blood, as it is written: "For their blood demands vengeance." Rabbi Abbahu said in the name of Rabbi Elazar, "Every righteous person whom the nations of the world kill, the Holy One, blessed be He, writes his name in His book, as it says: "He will judge among the nations, filling them with corpses."
And the Holy One, blessed be He, says to them, 'Why did you kill so-and-so?' And they deny it, saying, 'We did not kill him.' What does the Holy One, blessed be He, do? He brings out His book and judges them, giving them lashes. He has not forgotten the cry of the oppressed."
