be pleased that the angel whom thou didst ordain for me, to redeem me from all evil, may bless the children; and let my name be called upon them, and the names of my fathers Abrabam and Izhak. And as the fishes of the sea in multiplying are multiplied in the sea, so may the children of Joseph be multiplied abundantly in the midst of the earth.
The Redeeming Angel and the Fishes of the Sea
Targum Pseudo-Jonathan on Genesis 48:16
