And Aaron’s son Eleazar took to wife one of Putiel’s daughters, and she bore him Phinehas. Those are the heads of the ancestral houses of the Levites by their families.
Torah Temimah points to Sotah 43a / TT (verified).
מבנות פוטיאל — מאי פוטיאל? יוסף, ולמה נקרא שמו פוטיאל — שפטפט ביצרו.
English: “Of the daughters of Putiel” — What is Putiel? Yosef. And why was he called Putiel? Because he struggled with his inclination (pitpet beyitzro).

Chazal identify Putiel with Yosef, praised for mastering his inclination.
