What does Genesis 48:20 mean?
Jacob is giving a deathbed blessing to the two oldest sons of Joseph. In fact, Jacob is giving them the primary blessing. They are being honored even beyond Jacob's naturally-born oldest sons (Genesis 48:1–13). Joseph had been displeased that Jacob had done so with his right hand on the younger son's head instead of the firstborn. Jacob explained to Joseph that he did this intentionally. Though Manasseh will be greatly blessed, his younger brother Ephraim will be even greater and grow into a much larger people (Genesis 48:14–19).Now Jacob concludes his blessing on the two boys. Both will be greatly blessed. Both will be held up in Israel as an example of God's blessing and prayer for others to be blessed likewise: "May God make you as Ephraim and Manasseh." And yet, the verse ends with one more acknowledgement that Ephraim will be more blessed than his brother Manasseh.
