'Mother' in the Bible

And Absalom made Amasa captain of the host instead of Joab: which Amasa was a man's son, whose name was Ithra an 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, and be buried 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 shall seem good unto thee.

I am one of them that are peaceable and faithful in Israel: thou seekest to destroy a city and a mother in Israel: why wilt thou swallow up the inheritance of the LORD?
