To whom did she say "Alakata Na
What is the significance of "Alakata Na
Rashi: I will take sheaves of Leket (what falls during harvesting; it must be left for the poor).
Vilna Gaon (5): She began to collect immediately after coming from the road, without resting from her weariness, like lazy people do. Rather, she is an Eshes Chayil; she immediately went to finance her house.
Malbim: She will take only Leket, but not Shichechah and Pe'ah, unlike other Aniyim.
Why did she add "v'Asafti va'Amarim [Acharei ha'Kotzerim]"?
Rashi: I will gather [attached] sheaves of Shichechah (what the harvester overlooked).
Malbim: Everything that she gathered in order to make a pile, she made a pile of it. Do not say that she took [attached] sheaves. She was in back of the harvesters, close to them - they saw that she did not take anything improper.
Why does it say "Zeh Shivtah ha'Bayis Me'at"?
Vilna Gaon: She was collecting the entire day - this shows that she is an Eshes Chayil!
Malbim: There was a house in the field for workers to rest there. The entire day she did not rest, only a little now that Bo'az came. This is why she collected so much!
