Genesis 48:15 Meaning and Commentary

Genesis 48:15

And he blessed Joseph
In his sons who were reckoned for him, and became the heads of tribes in his room: and said, God before whom my fathers Abraham and Isaac did walk;
in whom they believed, whom they professed, and whom they feared, served, and worshipped, and with whom they had communion: the God which fed me all my long unto this day;
who had upheld him in life, provided for him all the necessaries of life, food and raiment, and had followed him with his goodness ever since he had a being, and had fed him as the great shepherd of the flock, both with temporal and spiritual food, being the God of his life, and of his mercies in every sense.

Genesis 48:15 In-Context

13 And he set Ephraim on his right side, that is, on the left side of Israel; forsooth he set Manasseh on his left side, that is, on the right side of his father; and he joined both to him. (And he put Ephraim on his right side, that is, on Jacob's left side; and he put Manasseh on his left side, that is, on his father's right side; and he brought them both close to him.)

14 Which held forth the right hand, and laid it on Ephraim's head, the younger brother; soothly he laid his left hand on Manasseh's head, that was the more through birth. Jacob changed his hands, (And Jacob put forth his right hand, and laid it on Ephraim's head, the younger brother; and he laid his left hand on Manasseh's head, who was the elder. Jacob had crossed his hands,)

15 and blessed his son Joseph , and said, God, in whose sight my fathers Abraham and Isaac went; God that feedeth me from my young waxing age till into this present day; (and then he blessed his son Joseph, and said, May God, in whose sight my fathers Abraham and Isaac walked; the God who hath fed me from my young age unto this present day;)

16 the angel that delivered me from all evils, bless these children, and my name be called on them, and the names of my fathers, Abraham and Isaac; and wax they in multitude on (the) earth. (yea, the Angel who delivered me from every evil, bless these boys, and may they be called by my name, and the names of my fathers, Abraham and Isaac; and may they grow into a multitude upon the earth.)

17 Forsooth Joseph saw that his father had set his right hand on the head of Ephraim, and he took that heavily, and he endeavoured him(self) to raise his father's hand, and take it from the head of Ephraim, and to bear it over upon the head of Manasseh. (And Joseph saw that his father had put his right hand on Ephraim's head, and he was displeased, and he endeavoured to raise up his father's hand, and take it from Ephraim's head, and to bear it over onto Manasseh's head.)
