'Handmaiden' in the Bible

Turn to me, and be gracious to me;Grant Your strength [Your might and the power to resist temptation] to Your servant,And save the son of Your handmaid.

Then Mary said, “Behold, I am the servant of the Lord; may it be done to me according to your word.” And the angel left her.

For he hath regarded the low estate of his handmaiden: for, behold, from henceforth all generations shall call me blessed.
