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.
When Saul discovered that Ahimelech had helped David, Ahimelech pointed out that he did so because of his loyalty to Saul. He understood that David was carrying out Saul’s business (9-15). Saul by now was furious beyond reason, and commanded that not only Ahimelech but all the priests of Nob be killed. Only Abiathar escaped, and he immediately went and joined David (16-23; see Psalms 52:0).
