'Maidens' in the Bible

Then said Boaz unto Ruth, Hearest thou not, my daughter? Go not to glean in another field, neither go from hence, but abide here fast by my maidens:

And Naomi said unto Ruth her daughter in law, It is good, my daughter, that thou go out with his maidens, that they meet thee not in any other field.

So she kept fast by the maidens of Boaz to glean unto the end of barley harvest and of wheat harvest; and dwelt with her mother in law.

And now is not Boaz of our kindred, with whose maidens thou wast? Behold, he winnoweth barley to night in the threshingfloor.
