Charles Ellicott Commentary Genesis 46:29

"And Joseph made ready his chariot, and went up to meet Israel his father, to Goshen; and he presented himself unto him, and fell on his neck, and wept on his neck a good while." — Genesis 46:29 (ASV)

He fell on his neck.—Most of the versions and commentators understand this to mean Joseph throwing himself on Jacob’s neck, but Maimonides says that a son would not take so great a liberty with his father. The Authorised Version seems to understand it to mean Jacob, and this gives the best and most natural sense. The preceding words are literally, and he appeared to him: that is, he came into his presence; upon this, Jacob fell on his neck and wept there “again and a gain.”
