'Mother' in the Bible

Absalom put Amasa in command of the army instead of Joab. Now Amasa was the son of a man named Ithra the Israelite, who had married Abigail the daughter of Nahash, [the half sister of David and] the sister of Zeruiah, Joab’s mother.

Please let your servant return, so that I may die in my own city [and be buried] by the grave of my father and mother. But here is your servant Chimham [my son]; let him cross over with my lord the king, and do for him what seems good to you.”

I am one of the peaceable and faithful in Israel. You are seeking to destroy a city, and a mother in Israel. Why would you swallow up (devour) the inheritance of the Lord?”
