Genesis 33:10

And Jakob said, Say not so, I beseech thee. If now I have found favor in thy eyes, accept my present from my hand; because I have seen the look of thy face, and it is to me as the vision of the face of thy angel; for, lo, thou art propitious to me.

FORASMUCH AS I HAVE SEEN THY FACE. Jacob said to him: “Take my present from me because I have seen your face, which to me is as one seeth the sight of an angel, ‘vatirtzeini’ (and thou wast pleased with me), as you indicated by accepting the present,” just as G-d ‘rotzeh’ (taketh pleasure) in them that fear Him, by accepting their offerings and sacrifices. This is similar to the verses: ‘Venirtzah’ (And it shall be favourably accepted) for him; Their burnt-offerings and their sacrifices shall be ‘leratzon’ (acceptable) upon Mine altar, this being associated with the expressions: Let him be ‘retzui’ (the favoured) of his brethren, And the light of Thy countenance, for ‘ratzitham’ (Thou wast favourable to them), For Thy servants ‘ratzu’ (take pleasure) in her stones., 102:15. All these forms of ratzah connote desire and pleasure in a matter. But Rashi wrote, “Because you have agreed to pardon my offense. Vatirtzeini, you are reconciled with me.” But I have already said that it was not advisable for Jacob to bring iniquity to remembrance.

כראות פני אלוקים, as is the custom when one is granted an audience by the people in high office. The Torah already commanded that when appearing in Jerusalem three times a year, the Israelite fulfilling this commandment must not appear before G’d empty-handed. (Exodus 23,15)

ותרצני, in order that you will receive me with goodwill. We have a similar construction in Maleachi 1,8 הירצך או הישא פניך?, This consideration also warrants my sending you a lavish gift.

ויאמר יעקב...כי על כן ראיתי, this is precisely why it is appropriate that you accept my gift for I give it to you wholeheartedly. When I looked at your face I recognised that it bears the same features as the angel whom I have encountered and who has blessed me. Yaakov alluded to that nocturnal encounter in order to make Esau afraid to harm him. Yaakov had learned from the effect an encounter with angel- albeit it in a nocturnal vision- had had upon Lavan, who had not dared to attack him (29.31) Esau was well aware that Yaakov was a righteous man ever since his youth and he did not hesitate to believe him when told that Yaakov had encounters with angels. When Yaakov flattered Esau that the latter’s features reminded him of the features of the angel he had had a dialogue with, this was an exaggeration, of course. We find a similar exaggeration in Samuel II 14,20 where the woman from Tekoah says to King David that “my lord is wise as an angel of G’d and he knows all that goes on in the land.”

ותרצני, it was a source of satisfaction for me. Alternatively, the word could mean: “after you have displayed your goodwill towards me.”
