'Mother' in the Bible

And Naomi saith to her two daughters-in-law, 'Go, turn back, each to the house of her mother; Jehovah doth with you kindness as ye have done with the dead, and with me;

And Boaz answereth and saith to her, 'It hath thoroughly been declared to me all that thou hast done with thy mother-in-law, after the death of thy husband, and thou dost leave thy father, and thy mother, and the land of thy birth, and dost come in unto a people which thou hast not known heretofore.
