‘And he blessed Joseph and said, “The God before whom my fathers Abraham and Isaac did walk, the God who has shepherded me all my life long until this day, the angel who has redeemed me from all evil, bless the lads, and let my name be named on them, and the name of my fathers Abraham and Isaac, and let them grow into a multitude in the midst of the earth.”
“He blessed Joseph.” This is no error. The two are being blessed as one and are being blessed in Joseph's stead. His blessing is for Joseph but imparted to his two sons. What greater blessing for Joseph than for his two sons to be brought within the covenant of Yahweh, El Shaddai?
The blessing is straightforward. The young men, the sons of an Egyptian mother and born outside the promised land, are brought within the covenant, receiving the name of the patriarchs who had received that covenant on them, and are to be full sons and share in its blessings and become great peoples. So does Jacob un-Egyptianise these two young Egyptian men.
His description of God is significant. He is the One before whom his fathers walked in love and obedience, He is the one who has been with Jacob all his life and provided him with help and sustenance, He is the angel (God in His earthly presence) who has delivered him from all evil. This possibly especially refers to his struggle at Peniel when his name was changed and his life as well.
We note that Jacob in all humility does not himself claim to have walked before God in love and obedience, although others may well have said it of him. He is too aware of his failings. Thus his gratitude is in what God has done for him. It is this God, the faithful God, from Whom he beseeches blessing.
“Redeemed me.” The idea is of one who buys back someone from another. It is the first mention of the concept which would become so important. Is he thinking of his deliverance from Laban and the evil he had planned for Jacob? Is he thinking of the change in Esau who had once planned evil against him? Is he thinking of the deliverance from the evil of dire famine? Possibly all of these, but they are centred in that moment when he wrestled with God and was for ever changed. It was God Who set him free and became his Redeemer, and has thus ensured his constant deliverance from evil, including the evil of his own heart.
