Abiathar was the son of the priest Ahimelech and the sole survivor of the massacre at Nob. He fled to David and served as a priest throughout David's reign, but was eventually deposed by Solomon because he supported Adonija as heir to the throne.
22Then David said to Abiathar, "That day, when Doeg the Edomite was there, I knew he would be sure to tell Saul. I am responsible for every life in your father's household.
11Will the citizens of Keilah hand me over to him? Will Saul come down, as your servant has heard? LORD, God of Israel, please tell your servant." And the LORD said, "He will come down."
Bringing the Ark of the Covenant back to Jerusalem
Abiathar and Zadok carried the Ark of the Covenant back to Jerusalem when David fled from Absalom, but David asked them to take the ark back to the city.
24Zadok was also there, and with him all the Levites, carrying the ark of the covenant of God. They set down the ark of God, and Abiathar offered sacrifices until all the people had finished leaving the city.
25Then the king said to Zadok, "Take the ark of God back into the city. If I find favor in the LORD's eyes, he will bring me back and let me see both it and his dwelling place again.
27The king also said to Zadok the priest, "Listen: go back to the city in peace, and take with you your son Ahimaaz and Jonathan son of Abiathar—your two sons.
16Now send word quickly and tell David: 'Do not spend the night in the plains of the wilderness, but cross over at once, or the king and all the people with him will be swallowed up.'"
17Jonathan and Ahimaaz were waiting at En-rogel, and a servant girl would go and bring them word, and they would go and report to King David, for they could not risk being seen entering the city.
19He has sacrificed great numbers of cattle, fattened calves, and sheep, and has invited all the king's sons, Abiathar the priest, and Joab the commander of the army, but he has not invited your servant Solomon.
25For today he has gone down and sacrificed great numbers of cattle, fattened calves, and sheep. He has invited all the king's sons, the commanders of the army, and Abiathar the priest, and right now they are eating and drinking in his presence and shouting, 'Long live King Adonijah!'
King Solomon removed Abiathar from the priesthood and banished him to his estate in Anathoth. This fulfilled the Lord's word concerning the house of Eli.
26To Abiathar the priest the king said, "Go to Anathoth, to your own fields. You deserve to die, but I will not put you to death now, because you carried the ark of the Lord GOD before my father David and shared in all my father's hardships."
