Genesis 48:17-20

17When Joseph saw that his father 1placed his right hand on Ephraim’s head, it displeased him; and he grasped his father’s hand to move it from Ephraim’s head to Manasseh’s head. 18And Joseph said to his father, “Not so, my father, for this one is the firstborn. Place your right hand on his head.” 19But his father refused and said, “I know, my son, I know; he also will become a people and he also will be great. However, his younger brother shall be greater than he, and 2his 3descendants shall become 4a multitude of nations.” 20So 5he blessed them that day, saying, “By you Israel will pronounce blessing, saying, ‘May God make you like Ephraim and Manasseh!’” And so he put Ephraim before Manasseh.
