18“Not so, my father!” Joseph said. “This one is the firstborn; put your right hand on his head.”
19But his father refused. “I know, my son, I know!” he said. “He too shall become a people, and he too shall be great; nevertheless, his younger brother shall be greater than he, and his offspring shall become a multitude of nations.”
20So that day Jacob blessed them and said:
“By you shall Israel pronounce this blessing:
‘May God make you like Ephraim and Manasseh.’” So he put Ephraim before Manasseh.
