Jacob's (messed up) blessing of Ephraim and Manasseh
1 And it came to pass after these things, that one told Joseph, Behold, thy father is sick: and he took with him his two sons, Manasseh and Ephraim.
2 And one told Jacob, and said, Behold, thy son Joseph cometh unto thee: and Israel strengthened himself, and sat upon the bed.
When Joseph heard that his father Jacob was sick, he went to visit him with his two sons, Manasseh and Ephraim.
3And Jacob said unto Joseph, God Almighty appeared unto me at Luz in the land of Canaan, and blessed me,
After they arrived, Jacob said,
God appeared to me in Canaan and blessed me. 
4 And said unto me, Behold, I will make thee fruitful, and multiply thee, and I will make of thee a multitude of people; and will give this land to thy seed after thee for an everlasting possession.
God said to me, "I will make you fruitful and give this land to your seed to possess forever."
5 And now thy two sons, Ephraim and Manasseh, which were born unto thee in the land of Egypt before I came unto thee into Egypt, are mine; as Reuben and Simeon, they shall be mine.
Your two sons, Ephraim and Manasseh, are now mine.
6 And thy issue, which thou begettest after them, shall be thine, and shall be called after the name of their brethren in their inheritance.
7 And as for me, when I came from Padan, Rachel died by me in the land of Canaan in the way, when yet there was but a little way to come unto Ephrath: and I buried her there in the way of Ephrath; the same is Bethlehem.
Any other children that you have will be yours.
8 And Israel beheld Joseph's sons, and said, Who are these?
9 And Joseph said unto his father, They are my sons, whom God hath given me in this place. And he said, Bring them, I pray thee, unto me, and I will bless them.
10 Now the eyes of Israel were dim for age, so that he could not see. And he brought them near unto him; and he kissed them, and embraced them.
11 And Israel said unto Joseph, I had not thought to see thy face: and, lo, God hath shewed me also thy seed.
12 And Joseph brought them out from between his knees, and he bowed himself with his face to the earth.
When Jacob saw Joseph's sons, he said,
Who are they?
13 And Joseph took them both, Ephraim in his right hand toward Israel's left hand, and Manasseh in his left hand toward Israel's right hand, and brought them near unto him.
Joseph brought his two sons to Jacob, with Ephraim toward Jacob's left hand, and Manasseh toward his right.
14 And Israel stretched out his right hand, and laid it upon Ephraim's head, who was the younger, and his left hand upon Manasseh's head, guiding his hands wittingly; for Manasseh was the firstborn.
15 And he blessed Joseph, and said, God, before whom my fathers Abraham and Isaac did walk, the God which fed me all my life long unto this day,
16 The Angel which 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; and let them grow into a multitude in the midst of the earth.
But Jacob put his right hand on the Ephraim's head, and his left hand on Manasseh's. (Manasseh was the older son.)
And he blessed them.
17 And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he held up his father's hand, to remove it from Ephraim's head unto Manasseh's head.
18 And Joseph said unto his father, Not so, my father: for this is the firstborn; put thy right hand upon his head.
When Joseph saw that Jacob put his right hand on the wrong head, it displeased him, and he tried to reverse Jacob's hands, saying,
You've messed up the blessing, father.
Put your right hand on the firstborn's head.
19 And his father refused, and said, I know it, my son, I know it: he also shall become a people, and he also shall be great: but truly his younger brother shall be greater than he, and his seed shall become a multitude of nations.
20 And he blessed them that day, saying, In thee shall Israel bless, saying, God make thee as Ephraim and as Manasseh: and he set Ephraim before Manasseh.
But Jacob refused, saying,
I know, I know.
Manasseh will become a people and he'll be great. But his younger brother will be greater and his seed will become a multitude of nations. 
And Jacob went on with the blessing.
21 And Israel said unto Joseph, Behold, I die: but God shall be with you, and bring you again unto the land of your fathers.
Then Jacob said,
I'm dying. But God will be with you and bring you to Canaan.
22 Moreover I have given to thee one portion above thy brethren, which I took out of the hand of the Amorite with my sword and with my bow.
I'm giving you more than I'm giving your brothers (which I forcibly took from the Amorites).
