Genesis 48
16 Ref the angel who has redeemed me from all evil, bless the lads, and let my name be named on them, and the name of my fathers Abraham and Isaac. Let them grow into a multitude in the midst of the earth."
17 Ref When Joseph saw that his father laid his right hand on the head of Ephraim, it displeased him. He held up his father's hand, to remove it from Ephraim's head to Manasseh's head.
18 Ref Joseph said to his father, "Not so, my father; for this is the firstborn; put your right hand on his head."
19 Ref His father refused, and said, "I know, my son, I know. He also will become a people, and he also will be great. However, his younger brother will be greater than he, and his seed will become a multitude of nations."
