The Gemara read the reference in to "one portion above your brothers" to mean that like a firstborn son, Joseph received a double portion. Rav Papa asked Abaye whether perhaps Jacob merely gave Joseph an extra palm tree. Abaye answered that demonstrated that Jacob intended that Joseph would get two full portions "even as Reuben and Simeon." Rabbi Ḥelbo asked Rabbi Samuel bar Naḥmani why Jacob took the firstborn's birthright from Reuben and gave it to Joseph. The Gemara answered by citing to show that Reuben lost the birthright when he defiled Jacob's bed. The Gemara asked why Joseph benefited from Reuben's disqualification. Rabbi Samuel bar Naḥmani responded with a parable of an orphan who was brought up by an adoptive father, and when he became rich, he chose to give to his adoptive father from his wealth. Similarly, because Joseph cared for Jacob, Jacob chose to give to Joseph. Rabbi Ḥelbo challenged that reason, arguing instead that Rabbi Jonathan said that Rachel should have borne the firstborn, as indicated by the naming of Joseph in , and God restored the right of the firstborn to Rachel because of her modesty. And a Baraita read the reference in to "my sword and . . . my bow" to mean Jacob's spiritual weapons, interpreting "my sword" to mean prayer and "my bow" to mean supplication.
