Genesis 48:18 Meaning and Commentary

Genesis 48:18

And Joseph said unto his father, not so, my father
It is not right, it should not so be, that the right hand should be put on the youngest, and the left hand on the eldest; for this [is] the firstborn;
directing him to Manasseh, and seeking to guide his hand towards him: put thy right hand upon his head;
Joseph was for proceeding according to the order of birthright, but Jacob was directed by a spirit of prophecy, as follows.

Genesis 48:18 In-Context

16 the Angel who has redeemed me from all harm— may he bless these boys. May they preserve my name and the names of Abraham and Isaac. And may their descendants multiply greatly throughout the earth.”

17 But Joseph was upset when he saw that his father placed his right hand on Ephraim’s head. So Joseph lifted it to move it from Ephraim’s head to Manasseh’s head.

18 “No, my father,” he said. “This one is the firstborn. Put your right hand on his head.”

19 But his father refused. “I know, my son; I know,” he replied. “Manasseh will also become a great people, but his younger brother will become even greater. And his descendants will become a multitude of nations.”

20 So Jacob blessed the boys that day with this blessing: “The people of Israel will use your names when they give a blessing. They will say, ‘May God make you as prosperous as Ephraim and Manasseh.’” In this way, Jacob put Ephraim ahead of Manasseh.
