פּירוש אויף רות 3:13

Stay the night. Stay over [one more night] without a husband.

"אם יגאלך טוב (if he will perform to thee the part of a kinsman, well):" Some say that "טוב" (Tov) was the name of the kinsman. However, if this were so, why does the text in the scroll later say, "Turn aside, sit down here, Ploni Almoni" (a certain someone)? Rather, its meaning is, if the kinsman will redeem you, it is good for you that he should redeem, because he is an important person.

As Adonoy lives. She said to him, “You are dismissing me with words [i.e., excuses].” He jumped up and swore to her¹⁸‘חי ה is the Biblical form of an oath, as in I Shmuel 19:6. that he would not dismiss her with words. Some of our Rabbis said that he swore to his evil inclination, for his evil inclination was inciting him [by saying], “You are not married and she is not married; be intimate with her.” So he swore that he would not be intimate with her except with marriage.
