Said Rabbi Ishmael: All these warnings and all these conditions were made known to and laid upon Samael the wicked, and he saith, ‘I have taken all upon me provided only that ten of the mighty shall be destroyed, to wit: Rabbi Akiva ben Joseph, and Rabbi Judah ben Baba, and Rabbi Jeshbab the scribe, and Rabbi Hananya ben Teradyon, Rabbi Hozpit the interpreter, Rabbi Elazar ben Shammua, Rabbi Hanina ben Hakinai, Rabbi Ishmael ben Elisha, Rabban Simon ben Gamaliel, Rabbi Eliezer ben Dama.’
