“And Abiathar shewed David that Saul had slain the LORD'S priests.”
King James Version (KJV)
Matthew Henry's Concise Commentary
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, Ps 91:1. In the hurry and distraction David was continually in, he found time for communion with God, and found comfort in it.
“And Isaac brought her into his mother Sarah's tent, and took Rebekah, and she became his wife; and he loved her: and Isaac was comforted after his mother's death.”
