Ramban on Genesis 47:5/רמב"ן על בראשית מ״ז:ה׳

1THY FATHER AND THY BRETHREN ARE COME UNTO THEE. This introduction is as if to say: “Now I have heard that your father and your brothers have come, and the land of Egypt is before you.” The correct interpretation appears to me to be that Pharaoh said to Joseph: “Your father and your brothers have come to you because they have heard of your glory, and it is upon you that they have cast their burden. See that you treat them well for it is your responsibility and it is within your power.”
