9 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. 10 And he inquired of the Lord for him, gave him provisions, and gave him the sword of Goliath the Philistine." 11 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. 12 And Saul said, "Hear now, son of Ahitub!" And he answered, "Here I am, my lord." 13 Then 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, that he should rise against me, to lie in wait, as it is this day?" 14 So Ahimelech answered the king and said, "And who among all your servants is as faithful as David, who is the king's son-in-law, who goes at your bidding, and is honorable in your house? 15 Did I then begin to inquire of God for him? Far be it from me! Let not the king impute anything to his servant, or to any in the house of my father. For your servant knew nothing of all this, little or much." 16 And the king said, "You shall surely die, Ahimelech, you and all your father's house!" 17 Then the king said to the guards who stood about him, "Turn and kill the priests of the Lord, because their hand also is with David, and because they knew when he fled and did not tell it to me." But the servants of the king would not lift their hands to strike the priests of the Lord. 18 And the king said to Doeg, "You turn and kill the priests!" So Doeg the Edomite turned and struck the priests, and killed on that day eighty-five men who wore a linen ephod. 19 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.
20 Now 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 Lord's priests. 22 So David said to Abiathar, "I knew that day, when Doeg the Edomite was there, that he would surely tell Saul. I have caused the death of all the persons of your father's house. 23 Stay with me; do not fear. For he who seeks my life seeks your life, but with me you shall be safe."

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.
