What do we learn from "va'Telach va'Savo va'Telaket"?
Torah Temimah citing Shabbos 113b: Rus kept coming and going until she found proper people to go with them.
Rashi citing Rus Rabah: She made signs on the roads before entering the field and returned to the city, lest she err on the paths and [not] know how to return.
Vilna Gaon: She went in the entire field without gathering. Why should she carry a heavy load back and forth? After reaching the end of the field, she returned and gathered until the city.
Malbim: She did not need to go far. She immediately came to Bo'az' field and began to gather, for it was near. Even though it was morning, which is one of the three times that they give out Pe'ah 1 (Pe'ah 4:5) in the corner of the field, she did not go to there. She alone took Leket (the other Aniyim were taking Pe'ah).
Malbim (2) said that they do not distribute, rather, everyone takes for himself! He means that the owner declares which areas are Pe'ah. (PF)
What is the meaning of "va'Yikar Mikreh"?
Rashi: She happened to come to Bo'az' field.
Malbim: Mikreh is something without a cause that makes it occur; it is due to Hashgachah. R. Eliezer requested "Hakre Na Lefanai?" (Bereishis 24:12) - Hashem should not wait until a cause obligates [the proper girl to come], rather, Hashgachah should bring her. Here, Hashem caused that the first field that she came to was of Bo'az, for he was from Elimelech's family. He was prepared to redeem and do Yibum, and Malchus Beis David would come from him.
