Genesis 48:18-19

King James Version

¹⁸ And Joseph said unto his father, Not so, my father: for this is the firstborn; put thy right hand upon his 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.
