He fell on his neck. — Most of the versions and commentators understand this of 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 of Jacob, and this gives the best and most natural sense. The preceding words literally are, and he appeared unto him: that is, came into his presence; whereupon Jacob fell on his neck, and wept there “again and again.”
Genesis 46:29
29 And Joseph made ready his chariot, and went up to meet Israel his father, to Goshen, and presented himself unto him; and he fell on his neck, and wept on his neck a good while.
