'Maid servants' in the Bible

And she saith, 'Let me find grace in thine eyes, my lord, because thou hast comforted me, and because thou hast spoken unto the heart of thy maid-servant, and I -- I am not as one of thy maid-servants.'

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.
