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 Joseph took his two sons, both Ephraim in his right hand, but on the left of Israel, and Manasse on his left hand, but on the right of Israel, and brought them near to him.
14 But Israel having stretched out his right hand, laid it on the head of Ephraim, and he was the younger; and his left hand on the head of Manasse, his hands crosswise.
15 And he blessed them and said, The God in whose sight my fathers were well pleasing, Abraam and Isaac, the God who continues to feed me from my youth until this day;
16 the angel who delivers me from all evils, bless these boys, and my name shall be called upon them, and the name of my fathers, Abraam and Isaac; and let them be increased to a great multitude on the earth.
17 And Joseph having seen that his father put his right hand on the head of Ephraim—it seemed grievous to him; and Joseph took hold of the hand of his father, to remove it from the head of Ephraim to the head of Manasse.
