וַתֹּאמֶר֩ ר֨וּת הַמּוֹאֲבִיָּ֜ה אֶֽל־נָעֳמִ֗י אֵֽלְכָה־נָּ֤א הַשָּׂדֶה֙ וַאֲלַקֳטָּ֣ה בַשִׁבֳּלִ֔ים אַחַ֕ר אֲשֶׁ֥ר אֶמְצָא־חֵ֖ן בְּעֵינָ֑יו וַתֹּ֥אמֶר לָ֖הּ לְכִ֥י בִתִּֽי׃
И Руфь Моавитянка сказала Наоми: 'Позвольте мне теперь пойти на поле и почерпнуть среди початков кукурузы того, в глазах которого я обрету благосклонность.' И она сказала ей: 'Иди, дочь моя.'
Rashi
Let me go now to the field. To one of the fields of the people of the city, after one of them, “in whose eyes I will find favor,” so that he will not rebuke me.
Ibn Ezra
After him in whose sight I shall find favour. Some say that the "vav" refers back to Boaz mentioned earlier, and the meaning is "perhaps it will be." In my opinion, the "vav" refers to the owner of the field, even though he is not mentioned, because of "and her chance happened," and its meaning is "coincidence."
Rashi
And glean among the stalks, behind one in whose eyes I will find favor. After someone in whose eyes I will find favor.6Alternatively, after I find favor in his eyes, i.e., I will not glean in a field until I know the owner allows it. (Malbim)
