Sforno on Genesis 32:21/ספורנו על בראשית ל״ב:כ״א

1ואמרתם גם הנה עבדך יעקב אחרינו, he told each of them to reply with the same words in addition to the words that each one had been instructed to answer individually. The purpose behind these detailed instructions was to convince Esau that Yaakov was indeed not far behind on his way to Seir the destination of these gifts which he had sent ahead of him.

2כי אמר אכפרה פניו במנחה, these were the words he had instructed the shepherds leading the gift to say, in order to soften Esau’s attitude by Yaakov assuming a somewhat servile attitude prior to their coming face to face with one another.

3אראה פניו, an expression denoting the “paying of a visit,” as we know from Exodus 34,23 where the Jewish people is instructed to visit the Temple three times annually with the same formula, i.e. יראה כל זכורך...ולא יראו פני ריקם, “every male of you is to visit Me; when they pay this visit they shall not come empty-handed.” Yaakov himself confirmed the meaning of the formula אראה פניך when he said to Esau in 33,10 על כן ראיתי פניך כראות פני אלוקים, “inasmuch as visiting you is akin to visiting the presence of G’d.” It was an accepted custom for a visitor to highly placed persons to arrive bearing gifts.
