Sforno on Genesis 33:10/ספורנו על בראשית ל״ג:י׳

1כראות 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)

2ותרצני, 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.
