'Mother' in the Bible

And Naomi said unto her two daughters-in-law, Go, return each of you to her mother's house: Jehovah deal kindly with you, as ye have dealt with the dead, and with me.

And Boaz answered and said unto her, It hath fully been showed me, all that thou hast done unto thy mother-in-law since the death of thy husband; and how thou hast left thy father and thy mother, and the land of thy nativity, and art come unto a people that thou knewest not heretofore.
