1 Samuel 22:19-21

19 Nob, the town of the kohanim, he struck with the edge of the sword: men and women, children and infants, oxen, asses, and sheep with the edge of the sword.

20 Yet one of the sons of Ahimelech son of Ahitub, named Abiathar, escaped and fled to David.

21 Abiathar told David that Saul had slain ADONAI’s kohanim.
