Genesis 48:13-20

Then Joseph took them both, Ephraim with his right hand toward Israel’s left, and Manasseh with his left hand toward Israel’s right, and brought them close to him. But Israel reached out his right hand and laid it on the head of Ephraim, who was the younger, and his left hand on Manasseh’s head, crossing his hands [intentionally], even though Manasseh was the firstborn. 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.
