וַיֹּאמַ֑ר אֲדֹנָ֗י אִם־נָ֨א מָצָ֤אתִי חֵן֙ בְּעֵינֶ֔יךָ אַל־נָ֥א תַעֲבֹ֖ר מֵעַ֥ל עַבְדֶּֽךָ׃
At sinabi niya, “Panginoon, kung ngayon ay nakasumpong ako ng biyaya sa iyong paningin, huwag ka sanang lumampas mula sa iyong lingkod.”
Rabbeinu Bahya
There is another Baraitha which discusses these phenomena describing three men walking together, the tallest in the middle, flanked by a גדול on his right and a קטן on his left. When the three angels visited Avraham (Genesis 18,3) the angel Michael was in the centre, Gavriel on his right, and Raphael on his left.

והיית לנו לעינים, “and you have become our eyes” this is to be understood as Genesis 18,3: אם נא מצאתי חן בעיניך “if only I will find favour in your eyes.” The word עינים is used in the same sense as פנים, “face, front.” An alternate interpretation: other potential converts to Judaism will look at you as the example that inspires them to follow his example. (B’chor shor)
