What Does Genesis 48:3 Mean?

And Jacob said to Joseph, "God Almighty appeared to me at Luz in the land of Canaan and blessed me." Jacob's speech to Joseph begins with the covenant foundation: God Almighty (El Shaddai) appeared at Luz (Bethel) and blessed him. The Bethel theophany (Genesis 28:13 to 15; 35:9 to 12) was the divine encounter that confirmed the Abrahamic promises to Jacob specifically: the land promise and the offspring promise and the divine presence promise. Jacob begins the blessing of Joseph's sons by invoking the authority behind what he is about to do: I am acting on the basis of what God promised me at Bethel.

"God Almighty" (El Shaddai) is specifically the divine name associated with covenant blessing and multiplication: the name used when God renewed the covenant with Abraham (Genesis 17:1) and with Jacob at Bethel (Genesis 35:11). By invoking El Shaddai, Jacob is placing the adoption and blessing of Joseph's sons within the covenant framework. He is not acting on mere patriarchal preference (though preference plays a role) but on the authority of the covenant promises that El Shaddai made to him at Bethel.

The Bethel appearance Jacob recounts: "appeared to me at Luz... and blessed me": is the spiritual credential for the patriarchal act he is about to perform. The dying patriarch is invoking the vision that authorized his covenant role: God appeared; God blessed; I am acting on the basis of that appearance and blessing. The blessing of Joseph's sons in chapter 48 flows from the Bethel theophany of chapters 28 and 35 as clearly as Isaac's blessing in chapter 27 flowed from Abraham's covenant in chapter 12.
