"Jacob, who redeemed Abraham"
Synopsis
We learn that Jacob redeemed Abraham just because God saw that Jacob would descend from Abraham. Rabbi Chizkiyah questions why Hananiah, Mishael and Azariah (who threw themselves into a burning fire) are referred to as descendants of Jacob, when in fact they were the descendants of Judah. Rabbi Shimon explains that is because in their time of danger they referred to Jacob, and God took note of this and protected them, and those who had ridiculed the name of Jacob were killed by the flame.
