Genesis 48:15,16

He blessed Joseph, and said. — In Jacob’s blessing there is a threefold appellation of the Deity, and a threefold blessing given to Joseph’s sons. God is, first, the Elohim before whom his fathers had walked. Next, He is the Elohim who, as a shepherd, had watched over Jacob all his life long. But, thirdly, He is that Divine Presence which had been, and still was, Jacob’s “goël,” redeeming and rescuing him from all evil. The blessing is first general, the verb “bless” being singular, which, following the threefold repetition of God’s name in the plural, is rightly used by Luther as a proof of a Trinity in Unity in the Godhead. Secondly, Ephraim and Manasseh are to bear the names, and be the representatives of Abraham, Isaac, and Jacob. Lastly, they are to grow into a multitude with extraordinary rapidity, the word used signifying that they were to increase with a prolificness as great as that of fishes.

The word “goël” is here used for the first time. It subsequently became the term for the nearest blood relative, whose duty it was to avenge a murder; but it is here used in its wider sense of a Saviour and a Deliverer. (Comp. Exodus 6:6; Isaiah 59:20, &c.) The angel who wrestled with Jacob cannot accurately be described as having appeared to him in the character of a deliverer (Genesis 32:24). He appeared as an adversary; and Jacob learned in the struggle, by overcoming him, that he had power with God and man, and would prevail over all the difficulties and foes that still stood in his way. Moreover, the verb is present, “the angel that redeemeth me from all evil.” Jacob recognised a Divine Presence which constantly guarded him, and which was ever his Redeemer and Saviour.
