Genesis 48:1, 5

Not long afterward, Joseph received the news that his father’s health was failing, so he took his two sons Manasseh and Ephraim along with him.

Furthermore, I will adopt as my very own your two sons who were born in the land of Egypt before I came here. Yes, I claim Ephraim and Manasseh as mine, no less than my two oldest, Reuben and Simeon.
