Genesis 48:22
20 So he blessed them that day, saying, “By you will Israel bless, saying,‘May God make you like Ephraim and Manasseh.’”Thus he put Ephraim before Manasseh. 21 Then Israel said to Joseph, “I am about to die, but God will be with you and will bring you back to the land of your fathers. 22 As one who is above your brothers, I've given you one shoulder40, which I took from the Amorites with my sword and my bow.”
1 Kings 12:25
24 ‘This is what the Lord has said: “Do not attack and make war with your brothers, the Israelites. Each of you go home. Indeed this thing has happened because of me.”’” So they obeyed the Lord’s message.

Notes and References
"... The word for a “shoulder” here in the Hebrew is shekem. That is, it is a pun in which Jacob gives his Joseph an extra “Shechem.” Shechem was Jeroboam's capital of the northern kingdom of Israel. It was located in one of the Joseph tribes’ territories (1 Kings 12:25). E, the northern source, thus conveys the favored status of the northern kingdom, just as J favors the status of the southern kingdom of Judah in Jacob’s deathbed blessing of Judah in the following chapter ..."
