Bereshis 48:17-19

Orthodox Jewish Bible

¹⁷ And when Yosef saw that aviv laid his yamin upon the rosh Ephrayim, it displeased him; and he took hold of yad aviv, to remove it from rosh Ephrayim unto rosh Menasheh.

¹⁸ And Yosef said unto aviv, Not so, Avi; for this is the bechor; put thy yamin upon his rosh.

¹⁹ And aviv refused, and said, I know it, beni (my son), I know it; he also shall become a people, and he also shall be great; but truly achiv hakaton shall be greater than he, and his zera shall become a multitude of Goyim.
