“The servant replied” [2:6]. And the servant who was supervising the reapers responded that she is a young woman from Moab. She had returned with Naomi from the plains of Moab. Our sages say, the servant answered, what do you mean Boaz that you consider the young woman so valuable? She has recently come from Moab. Boaz responded: she has a good teacher.46Ruth Rabbah, 4.9 That is to say, her mother- in-law Naomi who is very pious taught her much and she moved away from the ways of the Moabites. Therefore, it says in the verse, “she came back with Naomi from the country of Moab” [2:6]. That is to say, she removed herself from the deeds that were done in the land of Moab. She returned with Naomi who taught her.

Who returned with Naomi. The accent is at the beginning, under the shin, because it is the past tense, and not the present tense [of the verb].10See Rashi in Bereishis 29:6.
