'Servant' in the Bible

Then Boaz said to his servant who was in authority over the cutters, Whose girl is this?

And the servant who was in authority over the cutters said, It is a Moabite girl who came back with Naomi out of the country of Moab;

Then she said, May I have grace in your eyes, my lord, for you have given me comfort, and you have said kind words to your servant, though I am not like one of your servants.

And Naomi said to Ruth, her daughter-in-law, It is better, my daughter, for you to go out with his servant-girls, so that no danger may come to you in another field.

So she kept near the servant-girls of Boaz to take up the grain till the cutting of the early grain and the cutting of the late grain were ended; and she went on living with her mother-in-law.

And he said, Who are you? And she answering said, I am your servant Ruth: take your servant as wife, for you are a near relation.
