20 But one son of Ahimelek son of Ahitub, named Abiathar, escaped and fled to join David. 21 He told David that Saul had killed the priests of the Lord. 22 Then 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 the death of your whole family. 23 Stay with me; don't be afraid. The man who wants to kill you is trying to kill me too. You will be safe with me."

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.
