Pharaoh's invitation was as generous as it was because Pharaoh held Joseph in high regard. It was an invitation, not a command. Pharaoh had no authority to command Jacob to move into Egypt. Jacob was free to accept or reject this offer. If Jacob chose to accept it, he would be free to return to Canaan whenever he chose. The fact that Jacob's family could not leave Egypt once they settled there was due to a new Pharaoh's new policies concerning the Israelites as residents of Egypt. It was not due to the action of this Pharaoh (Sesostris III).
". . . when Pharaoh restates Joseph's offer and twice' gives the brothers the good' (vv. 18, 20) of the land of Egypt, it is hard not to see in the purpose of this narrative a conscious allusion to the good' (1:31) land given to Adam in Genesis 1. The picture of Joseph is a picture of restoration--not just the restoration of the good fortune of Jacob, but, as a picture, the restoration of the blessing that was promised through the seed of Jacob. This picture is also a blueprint for the hope that lies for the people of Israel at the end of the Pentateuch. They are to go into the land and enjoy it as God's good gift (e.g., Dt 30:5)."884
Joseph's admonition to his brothers not to quarrel on their journey (v. 24) is a bit unclear. Probably he meant just that, not to become involved in arguing and recriminations over the past (cf. Prov. 29:9). However the usual meaning of the Hebrew word is to fear (cf. Exod. 15:14). So part of his meaning may be that they should not be afraid of robbers as they returned to Canaan or fearful of returning to Egypt in the future.885
Jacob had suffered as a victim of his sons' deception and malice. He had also suffered because of his own failure to cling to the promises that God had given to his forefathers, himself, and Joseph in his dreams. Jacob always had difficulty believing without seeing. Nevertheless when he believed that Joseph was alive and ruling over Egypt, his spirit revived and he returned to a position of trust in God. For this reason Moses called him Israel again in the text (v. 28).886
