Manasseh’s

But Israel stretched out his right hand and put it on the head of Ephraim, the younger; and crossing his hands, he put his left on Manasseh’s head, although Manasseh was the firstborn.

When Joseph saw that his father had placed his right hand on Ephraim’s head, he was displeased and took his father’s hand to move it from Ephraim’s head to Manasseh’s.

Ephraim’s territory was to the south, and Manasseh’s was to the north, having the Sea as its border and adjoining Asher on the north and Issachar on the east.
