What does Genesis 48:7 mean?
Jacob, on his deathbed, is meeting with Joseph and Joseph's two oldest sons Ephraim and Manasseh (Genesis 41:50–52). Jacob has just made what may have been a startling announcement: He is claiming Joseph's two oldest sons as his own sons and elevating them to the rank of his oldest sons. As a result, Joseph's sons will receive the birthright and a double portion of the family inheritance (Genesis 48:1–6).There are several reasons why Jacob would do something so drastic. In part, he is holding his oldest two sons Reuben and Simeon accountable for their sins (Genesis 49:3–7). But now Jacob reveals another motive: his love and heartbreak over his late wife, Rachel (Genesis 29:18; 35:19; 37:3).
Jacob began this conversation with Joseph by remembering the promises God made to him at Bethel, also called Luz (Genesis 48:3–4). Immediately following that appearance from God, Jacob's beloved wife died in childbirth along the road while the family was traveling toward Bethlehem (Genesis 35:16–20). Jacob buried her body there and built a pillar over her grave.
Now Jacob, while blessing Joseph's sons, remembers that moment. Perhaps he is thinking of his own approaching death. Perhaps he is explaining how he wishes to honor her in elevating Joseph's sons to the level of his own sons. In a sense, this would increase the count of Rachel's "sons" from two to four. In any case, the loss of Rachel appears to be always near to Jacob's mind.
