EPHRAIM IS A MULTITUDE OF PEOPLE

Genesis 48:14 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.

Genesis 48:19 … his younger brother shall be greater than he and his seed shall become a multitude of nations.
