תּלמוד אויף דברים 12:25

Rebbi Shimon bar Rebbi says, behold the Torah says (Deuteronomy 12,23) "Only be steadfast in not eating blood, for blood is the soul. etc." And now if by blood, which a person naturally holds back from, one who separates himself from it receives reward, then by robbery and immorality which a person's natural inclination seeks out and wants, how much more so will one who separates from them receive reward and for generations and generations afterwards until the end of all generations.

Assume that it derives from Shmuel, who said: "Salted is like hot, pickled is like cooked."
