Genesis 48:18-20

Young's Literal Translation

¹⁸ and Joseph saith unto his father, `Not so, my father, for this [is] the first-born; set thy right hand on his head.'

¹⁹ And his father refuseth, and saith, `I have known, my son, I have known; he also becometh a people, and he also is great, and yet, his young brother is greater than he, and his seed is the fulness of the nations;'

²⁰ and he blesseth them in that day, saying, `By thee doth Israel bless, saying, God set thee as Ephraim and as Manasseh;' and he setteth Ephraim before Manasseh.
