Charles Ellicott Commentary Genesis 46:4

"I will go down with thee into Egypt; and I will also surely bring thee up again: and Joseph shall put his hand upon thine eyes." — Genesis 46:4 (ASV)

Joseph shall put his hand upon thine eyes. —Both among the Jews and Greeks it was the duty of those nearest in blood to close the eyes of a deceased relative. The promise conveyed the assurance that Jacob would die peacefully, surrounded by his friends. For the fulfillment see Genesis 1:1.
