פּירוש אויף רות 2:15

“She rose to glean” [2:15]. And Boaz said to his servants: let her gather between the rows and don’t embarrass her. We learn from this verse how one should give charity and not embarrass. This is the greatest charity that the poor person does not know from where he receives it. We find that our sages tied money in the back of their garments and let it fall, so that the poor would find it. Boaz also spoke to his servants; you should forget and not embarrass her.

Do not reproach her. Derived from the root שלל (to plunder). Some say it is like an error from [the word] של.
