What does Genesis 48:4 mean?
Jacob is ill and nearing the end of his life (Genesis 48:1–3). Joseph has brought his two sons to Jacob, presumably so the three of them could receive a blessing from the patriarch before his death. In the previous verse, Jacob began to recall the time God Almighty appeared to him at Bethel, also known as Luz. There, the Lord had blessed him (Genesis 28:12–15). This was when Jacob was returning to Canaan after spending two decades working for his father-in-law in Padan-aram while hiding from the wrath of his brother Esau (Genesis 27:41–43).Joseph, Manasseh, and Ephraim listen as Jacob continues to describe one of the central promises given to him by God. This is a key covenant God made with Jacob's grandfather Abraham (Genesis 17:8) and that his own father Isaac passed down to him for an inheritance (Genesis 28:3–4). God would make Jacob "to be fruitful and multiply." This meant that his offspring would be very numerous, starting with his own 12 sons and their sons after them. Next Jacob told Joseph that God said his family would become a company of peoples who would take "everlasting possession" of the land of Canaan.
Despite his habit of being fearful and negative, Jacob appears to have held on to this promise from God throughout his life. Now, on his deathbed, he means for Joseph to understand that the family's future blessing is in Canaan—not in Egypt.
