'Maidens' in the Bible

Then Boaz said to Ruth, “Listen carefully, my daughter. Do not go to glean in another field or leave this one, but stay here close by my maids.

Naomi said to Ruth, “It is good, my daughter, for you to go out [to work] with his maids, so that others do not assault you in another field.”

So she stayed close to the maids of Boaz, gleaning until the end of the barley and wheat harvests. And she lived with her mother-in-law.

Now Boaz, with whose maids you were [working], is he not our relative? See now, he is winnowing barley at the threshing floor tonight.
