1 Samuel 22:19-21

19 Saul also had all the other inhabitants of Nob, the city of priests, put to death: men and women, children and babies, cattle, donkeys, and sheep---they were all killed.

20 But Abiathar, one of Ahimelech's sons, escaped, and went and joined David.

21 He told him how Saul had slaughtered the priests of the LORD.
