1 Samuel 22:19-21

19 Then he attacked the town of Nob, where the priests had lived, and he killed everyone there — men, women, children, and babies. He even killed their cattle, donkeys, and sheep.

20 Ahimelech’s son Abiathar was the only one who escaped. He ran to David

21 and told him, “Saul has murdered the priests at Nob!”
