Genesis 48:19-20

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 1his 2descendants shall become a 3multitude of nations.” 204He blessed them that day, saying, “By you Israel will pronounce blessing, saying, ‘May God make you like Ephraim and Manasseh!’” Thus he put Ephraim before Manasseh.
