I Samuel 22:9-12, 20

Then answered Doeg the Edomite, who was set over the servants of Saul, and said, “I saw the son of Jesse going to Nob, to Ahimelech the son of Ahitub. And he inquired of the LORD for him, gave him provisions, and gave him the sword of Goliath the Philistine.” So the king sent to call Ahimelech the priest, the son of Ahitub, and all his father’s house, the priests who were in Nob. And they all came to the king. And Saul said, “Hear now, son of Ahitub!” He answered, “Here I am, my lord.”

Now one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped and fled after David.
