Genesis 48:15–20

15 And Jacob blessed the sons of Joseph, and said: God, in whose sight my fathers Abraham and Isaac walked, God that feedeth me from my youth until this day:

16 The angel that delivereth me from all evils, bless these boys: and let my name be called upon them, and the names of my fathers Abraham and Isaac; and may they grow into a multitude upon the earth.

17 And Joseph seeing that his father had put his right hand upon the head of Ephraim, was much displeased: and taking his father’s hand, he tried to lift it from Ephraim’s head, and to remove it to the head of Manasses.

18 And he said to his father: It should not be so, my father; for this is the firstborn, put thy right hand upon his head.

19 But he refusing, said: I know, my son, I know: and this also shall become a people, and shall be multiplied; but his younger brother shall be greater than he; and his seed shall grow into nations.

20 And he blessed them at that time, saying: In thee shall Israel be blessed, and it shall be said: God do to thee as to Ephraim, and as to Manasses. And he set Ephraim before Manasses.
