9 Then answered Doeg the Edomite, who stood by the servants of Saul, "I saw the son of Jesse coming to Nob, to Ahimelech the son of Ahitub, 10 and he inquired of the Lord for him and gave him provisions and gave him the sword of Goliath the Philistine." 11 Then the king sent to summon Ahimelech the priest, the son of Ahitub, and all his father's house, the priests who were at Nob, and all of them came to the king. 12 And Saul said, "Hear now, son of Ahitub." And he answered, "Here I am, my lord." 13 And Saul said to him, "Why have you conspired against me, you and the son of Jesse, in that you have given him bread and a sword and have inquired of God for him, so that he has risen against me, to lie in wait, as at this day?" 14 Then Ahimelech answered the king, "And who among all your servants is so faithful as David, who is the king's son-in-law, and captain over[1] your bodyguard, and honored in your house? 15 Is today the first time that I have inquired of God for him? No! Let not the king impute anything to his servant or to all the house of my father, for your servant has known nothing of all this, much or little." 16 And the king said, "You shall surely die, Ahimelech, you and all your father's house." 17 And the king said to the guard who stood about him, "Turn and kill the priests of the Lord, because their hand also is with David, and they knew that he fled and did not disclose it to me." But the servants of the king would not put out their hand to strike the priests of the Lord. 18 Then the king said to Doeg, "You turn and strike the priests." And Doeg the Edomite turned and struck down the priests, and he killed on that day eighty-five persons who wore the linen ephod. 19 And Nob, the city of the priests, he put to the sword; both man and woman, child and infant, ox, donkey and sheep, he put to the sword.
20 But one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped and fled after David. 21 And Abiathar told David that Saul had killed the priests of the Lord. 22 And David said to Abiathar, "I knew on that day, when Doeg the Edomite was there, that he would surely tell Saul. I have occasioned the death of all the persons of your father's house. 23 Stay with me; do not be afraid, for he who seeks my life seeks your life. With me you shall be in safekeeping."

Commentary on 1 Samuel 22:6-19
(Read 1 Samuel 22:6-19)
See the nature of jealous malice and its pitiful arts. Saul looks upon all about him as his enemies, because they do not just say as he says. In Ahimelech's answer to Saul we have the language of conscious innocence. But what wickedness will not the evil spirit hurry men to when he gets the dominion! Saul alleges that which was utterly false and unproved. But the most bloody tyrants have found instruments of their cruelty as barbarous as themselves. Doeg, having murdered the priests, went to the city, Nob, and put all to the sword there. Nothing so vile but those may do it, who have provoked God to give them up to their hearts' lusts. Yet this was the accomplishment of the threatenings against the house of Eli. Though Saul was unrighteous in doing this, yet God was righteous in permitting it. No word of God shall fall to the ground.
Commentary on 1 Samuel 22:20-23
(Read 1 Samuel 22:20-23)
David greatly lamented the calamity. It is great trouble to a good man to find himself any way the cause of evil to others. He must have been much pained, when he considered that his falsehood was one cause of this fatal event. David speaks with assurance of his own safety, and promises that Abiathar should have his protection. With the Son of David, all who are his may be sure they shall be in safeguard, Psalm 91:1. In the hurry and distraction David was continually in, he found time for communion with God, and found comfort in it.
