The Lord comforts Jacob with the assurance: ‘into a great nation I will establish you there.’ The historical unfolding of events demonstrated that Jacob's move to Egypt would not hinder the promise of a large lineage. The Hebrews entered Egypt as 75 individuals (Genesis 46:27), yet by the time of their exodus, their numbers had grown to 600,000, not counting women, children, the elderly, and foreigners. The more the Egyptians afflicted them after Joseph's death, the more they flourished under God’s blessing (Ex. 1:12).
Additionally, Jacob might have worried about hardships or even his own demise during the arduous journey, particularly given his advanced age. The Lord reassured him by promising His presence throughout the journey: ‘I will go with thee into Egypt.’ Jacob may have felt uncertainty about how God’s pledge that his offspring would inherit the land of Canaan (Genesis 28:13-14) could materialize while he was leaving that territory for another. The Lord offered reassurance with the promise: ‘I will bring you up again,’ indicating that just as He would accompany Jacob to Egypt, He would ultimately lead his descendants back from Egypt to the land that was promised to him and to his forefathers, Abraham and Isaac. Concerning Jacob personally, the Lord said, “Joseph shall put his hands upon your eyes,” meaning that although Jacob would pass away in Egypt alongside his son Joseph, he would find comfort in knowing that not a stranger, but his beloved son, whom he believed dead, would be there to care for him in his final moments and close his eyes at death.
