1 Samuel 22:19-21

19 And Nob, the city of the priests, he smote with the edge of the sword, both men and women, sons and sucklings, and oxen and donkeys and sheep, with the edge of the sword.

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

21 And Abiathar told David that Saul had slain LORD's priests.
