Genesis 48:15-22

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.
18 And Joseph said to his father, Not so, father; for this is the first-born; lay thy right-hand upon his head.
19 And he would not, but said, I know it, son, I know it; he also shall be a people, and he shall be exalted, but his younger brother shall be greater than he, and his seed shall become a multitude of nations.
20 And he blessed them in that day, saying, In you shall Israel be blessed, saying, God make thee as Ephraim and Manasse; and he set Ephraim before Manasse.
21 And Israel said to Joseph, Behold, I die; and God shall be with you, and restore you to the land of your fathers.
22 And I give to thee Sicima, a select portion above thy brethren, which I took out of the hand of the Amorites with my sword and bow.

Genesis 48:15-22 Meaning and Commentary

INTRODUCTION TO GENESIS 48

Joseph, hearing that his father Jacob was sick, paid him a visit, Ge 49:1,2; at which time Jacob gave him an account of the Lord's appearing to him at Luz, and of the promise he made unto him, Ge 49:3,4; then he adopted his two sons, Ephraim and Manasseh, and blessed them, and Joseph also, Ge 49:5-16; and whereas he crossed his hands when he blessed the sons of Joseph, putting his right hand on the youngest, and his left hand on the eldest, which was displeasing to Joseph, he gave him a reason for so doing, Ge 49:17-20; and then assured him that God would bring him, and the rest of his posterity, into the land of Canaan, where he assigned him a particular portion above his brethren, Ge 49:21,22.
