Genesis 48:18 In-Context

16 The angel who has been my saviour from all evil, send his blessing on these children: and let my name and the name of my fathers, Abraham and Isaac, be given to them; and let them become a great nation in the earth.

17 Now when Joseph saw that his father had put his right hand on the head of Ephraim, it did not seem right to him; and lifting his father's hand he would have put it on the head of Manasseh.

18 And Joseph said to his father, Not so, my father, for this is the older; put your right hand on his head.

19 But his father would not, saying, I am doing it on purpose, my son; he will certainly become a nation and a great one; but his younger brother will be greater than he, and his seed will become a great family of nations.

20 So he gave them his blessing that day, saying, You will be the sign of blessing in Israel, for they will say, May God make you like Ephraim and Manasseh; and he put Ephraim before Manasseh.
