'Maid servant' in the Bible

Then she said, “Let me find favor in your sight, my lord, for you have comforted me and have spoken kindly to your maidservant, though I am not as one of your maidservants.”

So he said, “Who are you?” And she answered, “I am Ruth your maid. Spread the hem of your garment over me, for you are a close relative and redeemer.”
