'Maid servants' in the Bible

And Naomi said to Ruth her daughter-in-law, "[It is] good, my daughter, that you go out with his maidservants so that you will not {be bothered} in another field."

So she stayed close with the maidservants [of] Boaz to glean until the end of the barley harvest and wheat harvest. And she lived with her mother-in-law.

So then, [is] not Boaz our kinsman whose maidservants you were with? Look, he [is] winnowing the barley at the threshing floor tonight.
