Genesis 48:16

13 And he set Ephraim on his right hand, that is, towards the left hand of Israel; but Manasses on his left hand, to wit, towards his father's right hand, and brought them near to him.

14 But he, stretching forth his right hand, put it upon the head of Ephraim, the younger brother; and the left upon the head of Manasses, who was the elder, changing his hands.

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.
