Genesis 33:4

And Esau Esau's conduct on this occasion is that of a good-natured and forgiving disposition. There is no statement of his having intended any mischief to Jacob. His appearance with four hundred men seems to have been accidental, and not with hostile intent against Jacob. He behaves throughout magnanimously and simply.

fell on his neck In Genesis 45:14; Genesis 46:29 (J), this demonstration of feeling is followed by "weeping."

kissed him On the Hebrew word for "kissed him" the Massoretic, or traditional, Hebrew text has this note: "All of it punctuated," i.e. every letter dotted. Probably the text was at an early date uncertain. The Rabbinic explanation is strange, i.e. "because he did not come to kiss him, but to bite him," and the tradition goes on to say that Jacob's neck was turned into marble!

they wept The strong emotion of orientals; cf. Genesis 45:2.

The Targum of pseudo-Jonathan, following up the absurd Rabbinic tradition arising from the Israelite hatred of Edom, explains that Jacob wept because his neck was painful, and Esau because he had pain in his teeth!
