NUM21 … the word "jealous" occurs four separate times in the discussion of the suspected unfaithful wife, the Sotah [this and following verse; Numbers 5:29]. The husband is jealous of his wife's lover, whom he suspects had sexual relations with his wife. The offering that she must bring is called the "Mincha of jealousy," and the summation of the portion is called the "Torah of jealousies." Rabbi Elazar Hakapar points out that jealousy is one of three negative character traits that can remove a person from this world, either due to his anguish or as a punishment (Mishnah, Avot 4:21). The Rabbis say that jealousy actually tears up the person inside (makes a person's bones rot), while a non-jealous person will never suffer this fate (Shabbat 10a). As much as this trait is undesirable in Judaism, the Rabbis also recognized it is a common emotion, even among Rabbis themselves. The Talmud thus declares that if two Rabbinic scholars live in the same city but do not get along in Torah law, one should die and the other should be exiled (Sotah 49a). Another passage says that this jealousy among Rabbis also causes Divine displeasure (Ta'anit 8a).
