Genesis 48:17-22

17When Joseph saw that his father laid his right hand on Ephraim’s head, it displeased him [because he was not the firstborn]; and he grasped his father’s hand to move it from Ephraim’s head to Manasseh’s head.

18Joseph said to his father, “Not so, my father, for this is the firstborn; place your right hand on Manasseh’s head.”

19But his father refused and said, “I know, my son, I know; Manasseh also will become a people and he will be great; but his younger brother shall be greater than he, and his descendants shall become a multitude of nations.”

20Then Jacob blessed them that day, saying, “By you Israel will pronounce a blessing, saying, ‘May God make you like Ephraim and Manasseh.’ ” And he put Ephraim before Manasseh.

21Then Israel said to Joseph, “Behold, I am about to die, but God will be with you, and bring you back to [Canaan] the land of your fathers.

22Moreover, I have given you [the birthright,] one portion [Shechem, one mountain ridge] more than any of your brothers, which I took [reclaiming it] from the hand of the Amorites with my sword and with my bow.”
