פּירוש אויף רות 2:19

“Her mother-in-law said to her” [2:19]. Her mother-in-law said to her: where did you gather and where did you work today? May the person who recognized you be blessed. She told her mother-in-law what she had done and the name of the man for whom she worked was Boaz. Our sages learn from this verse much more than, Ruth said to her mother-in-law, the name of the man where I worked was Boaz. The truth is that she did not work for Boaz. However, the verse teaches us that when the householder does something good for the poor person, the poor person does much more good for the householder. His house becomes blessed many times over through the poor person. Therefore, Ruth said: “the man with whom I worked today was Boaz” [2:19]. This means that I worked with Boaz and he did much good for me. He gave me a chunk of bread from his table. When the householder does not do good for the poor person, then he is punished through the poor person. The sages say that when the Holy One wants to take revenge on the nations of the world, He gives Israel into their hands. When He wants to take revenge on Israel, He does it through the hands of the poor, as the verse says, “he will cry out to the Lord against you, and you will incur guilt” [Deuteronomy, 15:9]. This means, as soon as you won’t give to the poor person, and he will call to God and it will be a sin for you. When the poor person stands at your door, the Holy One stands at the right side of the poor person. If the householder does good for the poor person, the Holy One blesses him immediately. If it is the opposite, the Holy One will be well recompensed by him.⁵⁴Ruth Rabbah, 5.9.

Blessed be he that took note of you. [I.e.,] the owner of the field who showed you favor [and allowed you] to glean in his field.¹⁹Alternatively, the person who takes note of you and marries you will be blessed because you are a gifted person. (Gra).
