In the face of tragedy, we sometimes forget how much God is with us. Jacob didn’t believe that he had seen the great events reported in the stories of his father and grandfather (cf. 47:9), not knowing that subsequent generations would tell his story along with theirs. When we have come through the trials and look back, however, we often can see God’s faithfulness. If we do not recognize it in this life, it will be openly evident in the world to come; but it’s often there for us if we have eyes to see. News of Joseph’s survival and flourishing transforms Jacob. Broken by the loss of his wife and son, Jacob now gets new eyes to see.
Jacob sets out for Egypt, to be reunited with his son before Jacob dies (45:28). When Jacob reaches Beersheba, he sacrifices (46:1). The narrator deems this site important, reiterating it in 46:5; Jacob, his father Isaac and grandfather Abraham had all sojourned there (21:31-33; 22:19; 26:23, 33; 28:10), and both Abraham and Isaac had called the site Beersheba (“Well of the Oath”) because of covenants sworn there (21:31; 26:31-33). (Jacob sacrificed for a different covenant elsewhere, in 31:54.) This was one of the sites where Abraham had called on the Lord’s name (21:33). Of course, Beersheba appears here rather than other sacred sites such as Bethel because Beersheba is in the south, on the way toward Egypt. But it would also mark the southern border of the land of Israel (cf. e.g., 1 Sam 3:20; 1 Kgs 4:25), a place where Jacob’s descendants could also remember God’s works.
In the ancient Near East, people more often expected divine dreams when they slept in sacred places. Whether this is a dream or a vision while awake (cf. 15:1, 12), it is consistent with how God had often spoken through dreams, including to Jacob (28:12; 31:10-11) and to Joseph (37:5-10) and to those whose dreams Joseph interpreted (40:5; 41:1, 5). God here calls Jacob’s name twice (46:2), as he had when calling Abraham (22:11; at the sacrifice of Jacob’s father Isaac); Abraham also appropriately replied, “Here I am” (22:11). “Here I am” was an appropriate response to God or his angel (22:1, 11), and had been Jacob’s response earlier (31:11). (The same pattern holds mostly true in Exod 3:4; 1 Sam 3:10.)
God identifies himself to Jacob as “the God of your father” (Gen 46:3), just as God revealed himsef to Isaac as “the God of your father Abraham” (26:24) and to Jacob as “the God of your father Abraham and the God of Isaac” (28:13). God encouraging Jacob not to fear (46:3) also recalls earlier revelations. God had urged Abram not to fear, because God would defend him (15:1); the angel of God warned Hagar not to fear (21:17); in the closest parallel to this passage, when the Lord appears at night to Isaac and assures him that he is the God of his father Abraham, God urges Isaac not to fear, because God is with him and will multiply him (26:24).
Although God had earlier warned Isaac against going down to Egypt (26:2), this time Jacob should not fear to go down to Egypt, because God will be with him (46:4) and will bring him back up (46:4). That Joseph will close his father’s eyes (46:4) assures Jacob of his reunion with Joseph; it also hints that God bringing Jacob back to Canaan does not mean during Jacob’s lifetime. Not all of God’s promises are always fulfilled directly in our individual lives; sometimes they are fulfilled in the legacy that, by God’s grace, we get to leave behind. (That “Jacob” in ancient ideology included Jacob’s family seems implied even in 46:5, where not only Jacob but his sons’ children and wives ride the wagons sent to carry “him,” singular, i.e., Jacob.)
God’s promises are faithful. God is dependable.
