'Mother' in the Bible

And Absalom set Amasa over the host instead of Joab; which Amasa was the son of a man whose name was Jithra the Israelite, that went in to Abigail the daughter of Nahash, sister to Zeruiah, Joab's mother.

Let thy servant, I pray thee, turn back again, that I may die in mine own city, by the grave of my father and of my mother. But behold thy servant Chimham: let him go over with my lord the king; and do to him what seems good to thee.

I am peaceable and faithful in Israel: thou seekest to destroy a city and a mother in Israel. Why wilt thou swallow up the inheritance of Jehovah?
