Genesis 48:16

the Angel, the Son of God, who had assisted his fathers as well as himself at various times, which redeemed me from all evil, both of body and of soul, bless the lads; and let my name be named on them and the name of my fathers Abraham and Isaac; in them the dignity and the faith of the patriarchs was to be continued, in them God's gifts of grace and salvation should be renewed, even as they had been received by their fathers; and let them grow into a multitude in the midst of the earth, their increase should be as great as that of the fishes in the sea. Thus did Jacob confess his heartfelt gratitude to God, both as his Shepherd and as his Savior, and the threefold mention of God may well have reference to the Trinity.
