Genesis 48:18 in the King James Version
And Joseph said unto his father, Not so, my father: for this is the firstborn; put thy right hand upon his head.
Context
17 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 Joseph said to his father, “Not so, my father, for this is the firstborn. Put your right hand on his head.”
19 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 offspring will become a multitude of nations.”
