1. Mose 48:5

Adoption of Joseph's Sons. - Gen 48:1, Gen 48:2. After these events, i.e., not long after Jacob's arrangements for his burial, it was told to Joseph (ויּאמר "one said," cf. Gen 48:2) that his father was taken ill; whereupon Joseph went to him with his two sons, Manasseh and Ephraim, who were then 18 or 20 years old. On his arrival being announced to Jacob, Israel made himself strong (collected his strength), and sat up on his bed. The change of names is as significant here as in Gen 45:27-28. Jacob, enfeebled with age, gathered up his strength for a work, which he was about to perform as Israel, the bearer of the grace of the promise.

The time drawing nigh that Israel must die, having, in the former chapter, given order about his burial, in this he takes leave of his grand-children by Joseph, and in the next of all his children. Thus Jacob's dying words are recorded, because he then spoke by a spirit of prophecy; Abraham's and Isaac's are not. God's gifts and graces shine forth much more in some saints than in others upon their death-beds. The Spirit, like the wind, blows where it listeth. In this chapter, I. Joseph, hearing of his father's sickness, goes to visit him, and takes his two sons with him (Gen 48:1, Gen 48:2). II. Jacob solemnly adopts his two sons, and takes them for his own (Gen 48:3-7). III. He blesses them (Gen 48:8-16). IV. He explains and justifies the crossing of his hands in blessing them (Gen 48:17-20). V. He leaves a particular legacy to Joseph (Gen 48:21, Gen 48:22).

48:5-7 Jacob, prompted by his memory of Rachel (see 35:16-20), blessed Joseph by elevating his two sons as coheirs with his other sons—the tribes of Ephraim and Manasseh would have shares along with the other tribes that came from Jacob (see Josh 16–17). Jacob also gave Ephraim, Joseph’s younger son, the birthright (see 1 Chr 5:1-2). As a result of this blessing, Ephraim and Manasseh became large and powerful tribes (see Josh 17:14-18).
