Abiathar

"(About Saul) Also Nob, the city of the priests, he struck with the edge of the sword, both men and women, children and nursing infants, oxen and donkeys and sheep—with the edge of the sword."

"Now it happened, when Abiathar the son of Ahimelech fled to David at Keilah, that he went down with an ephod in his hand. [...] When David knew that Saul plotted evil against him, he said to Abiathar the priest, “Bring the ephod here.”"

"And to Abiathar the priest the king said, “Go to Anathoth, to your own fields, for you are deserving of death; but I will not put you to death at this time, because you carried the ark of the Lord God before my father David, and because you were afflicted every time my father was afflicted.” So Solomon removed Abiathar from being priest to the Lord, that he might fulfill the word of the Lord which He spoke concerning the house of Eli at Shiloh."
