15 And he blessed Joseph and said, "The God before whom my fathers Abraham and Isaac walked, the God who has been my shepherd all my life long to this day, 16 the angel who has redeemed me from all evil, bless the boys; and in them let my name be carried on, and the name of my fathers Abraham and Isaac; and let them grow into a multitude[1] in the midst of the earth." 17 When Joseph saw that his father laid his right hand on the head of Ephraim, it displeased him, and he took his father's hand to move it from Ephraim's head to Manasseh's head. 18 And Joseph said to his father, "Not this way, my father; since this one is the firstborn, put your right hand on his head." 19 But his father refused and said, "I know, my son, I know. He also shall become a people, and he also shall be great. Nevertheless, his younger brother shall be greater than he, and his offspring shall become a multitude[2] of nations." 20 So he blessed them that day, saying, "By you Israel will pronounce blessings, saying, 'God make you as Ephraim and as Manasseh.'"Thus he put Ephraim before Manasseh.

The two good men own God in their comforts. Joseph says, They are my sons whom God has given me. Jacob says, God hath showed me thy seed. Comforts are doubly sweet to us when we see them coming from God's hand. He not only prevents our fears, but exceeds our hopes. Jacob mentions the care the Divine providence had taken of him all his days. A great deal of hardship he had known in his time, but God kept him from the evil of his troubles. Now he was dying, he looked upon himself as redeemed from all sin and sorrow for ever. Christ, the Angel of the covenant, redeems from all evil. Deliverances from misery and dangers, by the Divine power, coming through the ransom of the blood of Christ, in Scripture are often called redemption. In blessing Joseph's sons, Jacob crossed hands. Joseph was willing to support his first-born, and would have removed his father's hands. But Jacob acted neither by mistake, nor from a partial affection to one more than the other; but from a spirit of prophecy, and by the Divine counsel. God, in bestowing blessings upon his people, gives more to some than to others, more gifts, graces, and comforts, and more of the good things of this life. He often gives most to those that are least likely. He chooses the weak things of the world; he raises the poor out of the dust. Grace observes not the order of nature, nor does God prefer those whom we think fittest to be preferred, but as it pleases him. How poor are they who have no riches but those of this world! How miserable is a death-bed to those who have no well-grounded hope of good, but dreadful apprehensions of evil, and nothing but evil for ever!
