'Handmaids' in the Bible

but afterwards they turned, and caused the servants and the handmaids, whom they had let go free, to return, and brought them into subjection for servants and for handmaids.

but ye turned and profaned my name, and caused every man his servant, and every man his handmaid, whom ye had let go free at their pleasure, to return; and ye brought them into subjection, to be unto you for servants and for handmaids.
