כי אתך נשוב לעמך. ר״ל שלא יפרדו מעמה והוא ישראל ולזה ישובו אתה אע״פ שאין לה בנים. והנה ידמה כי נתגיירו כשנשאום מחלון וכליון ולזה לא מצאנו ברות שתצטרך להתגייר כשנשאה בועז ולזאת הסבה גם כן היו שבות אתה ולזה אמרו כי אתך נשוב לעמך אך רצתה נעמי לבחן אם נתגיירו מאהבת ה' יתברך או נתגיירו מצד חשקם בבניה: "Because with you we will return to your people" — meaning, they will not separate from her people, who are Israel, and therefore they will return with her even though she has no sons. It seems that they converted when Mahlon and Chilion married them, which is why we do not find that Ruth needed to convert when Boaz married her. For this reason, they were also returning with her. This is why they said, "Because with you we will return to your people." However, Naomi wanted to test if they had converted out of love for God or if they had converted due to their desire for her sons.
