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;

Genesis 48:18 In-Context

16 may the Messenger, who has rescued me from all evil, bless these boys. May they be called by my name and by the names of my grandfather Abraham and my father Isaac. May they have many children on the earth."

17 When Joseph saw that his father had put his right hand on Ephraim's head, he didn't like it. So he took his father's hand in order to move it from Ephraim's head to Manasseh's.

18 Then he said to his father, "That's not right, Father! This is the firstborn. Put your right hand on his head."

19 His father refused and said, "I know, Son, I know! Manasseh, too, will become a nation, and he, too, will be important. Nevertheless, his younger brother will be more important than he, and his descendants will become many nations."

20 That day he blessed them. He said, "Because of you, Israel will speak this blessing, 'May God make you like Ephraim and Manasseh!'" In this way Israel put Ephraim ahead of Manasseh.
