Genesis 48:15-20

Then Jacob (Israel) blessed Joseph, and said, “The God before whom my fathers Abraham and Isaac walked [in faithful obedience], The God who has been my Shepherd [leading and caring for me] all my life to this day, The Angel [that is, the LORD Himself] who has redeemed me [continually] from all evil, Bless the boys; And may my name live on in them [may they be worthy of having their names linked with mine], And the names of my fathers Abraham and Isaac; And may they grow into a [great] multitude in the midst of the earth.” When Joseph saw that his father laid his right hand on Ephraim’s head, it displeased him [because he was not the firstborn]; and he grasped his father’s hand to move it from Ephraim’s head to Manasseh’s head. Joseph said to his father, “Not so, my father, for this is the firstborn; place your right hand on Manasseh’s head.” But his father refused and said, “I know, my son, I know; Manasseh also will become a people and he will be great; but his younger brother shall be greater than he, and his descendants shall become a multitude of nations.” Then Jacob blessed them that day, saying, “By you Israel will pronounce a blessing, saying, ‘May God make you like Ephraim and Manasseh.’ ” And he put Ephraim before Manasseh.
