Genesis 46:4

‘I will bring you back again.’ The word ‘you’ does not mean Jacob himself. It means the nation that Jacob would become. So it means Jacob’s *descendants. Jacob himself would not return. But when he was dead, his body would return. And his sons would bury him in *Canaan.

In the phrase ‘when you die’, the word ‘you’ does mean Jacob himself. ‘Joseph’s hand shall close your eyes.’ That means that Jacob would die in peace. And Joseph would be with him. So Joseph would close Jacob’s eyes when he died. That was a son’s duty.

v5 Then Jacob set out from Beer-sheba. And Israel’s sons carried Jacob their father. And they carried their children and their wives. They carried them in the wagons that *Pharaoh had sent for them. v6 They also took their cows and their possessions, which they had gained in *Canaan. And they came into Egypt. Jacob and all his family came with him into Egypt. v7 He brought his sons and his sons’ sons. He brought his daughters and his sons’ daughters. He brought all his family with him into Egypt.
