'Mother' in the Bible

Absalom had appointed Amasa in place of Joab over the army. Now Amasa [was] the son of a man whose name [was] Ithra the Israelite, {who had married} Abigail the daughter of Nahash the sister of Zeruiah, the mother of Joab.

Please let your servant return, and let me die in my city in the tomb of my father and my mother. Here [is] your servant Kimham; let him cross over with my lord the king, and do for him that which [is] good in your eyes."

I [am] one of the faithful representatives of Israel. You [are] seeking to destroy a city and a mother in Israel. Why do you want to swallow the inheritance of Yahweh?"
