each wife lost (by the transaction) and each gained. Leah lost the mandrakes and gained the tribes (of Issachar and Zebulun) while Rachel gained the mandrakes and lost the tribes (of Issachar and Zebulun). (And some say Leah lost the birthright and Rachel gained the birthright. The birthright belonged to Reuben, but as a punishment for Reuben's causing this transaction, the birthright was taken from him and given to Joseph.) Rabbi Samuel ben Nahman said that Leah lost mandrakes and gained (two) tribes and the privilege of burial with Jacob, while Rachel gained mandrakes and lost the tribes and burial with Jacob.

Rebbi (or some say Rabbi Judah ben Pazi) said in the name of the academy of Yannai that Dinah was originally conceived as a boy, but when Rachel prayed for another son in , God transformed Dinah's fetus into a girl, and that is why
