1 Samuel 22:19

And Nob, &c. In the madness of his self-willed fury Saul wreaked upon an innocent city in his own kingdom the vengeance he had failed to execute upon a guilty heathen nation at God's command (1 Samuel 15:3). Thus the doom upon the house of Eli (1 Samuel 2:31) received a fresh fulfilment. So heavy a blow was inflicted upon the family of Ithamar, that when David organized the courses of the priests for the temple service only eight "chief men" could be found in it, against sixteen in the family of Eleazar (1 Chronicles 24:4).
