Jealousy among the tribes

Hi,

[Leah named her son ראובן Reuven, which may be parsed as “ראו בן,” “See, a son.”]

“Leah declared, ‘See the difference between my son and the son of my father-in-law. My father-in-law’s son [Esav] sold his birthright with full knowledge… and regarding him it is written, ‘And Esav hated Yaakov’…

“But my son, even though Yosef took my son’s birthright from him against his will… he was not jealous, as it is written, ‘And Reuven heard, and saved [Yosef] from their hands.’”

(Talmud, Berachot 7b)

Have a great day,
Mordechai
