17 And the king said to the couriers that stood about him, Turn and put the priests of Jehovah to death; because their hand also is with David, and because they knew when he fled, and did not inform me. But the servants of the king were not willing to put forth their hand to fall on the priests of Jehovah. 18 And the king said to Doeg, Turn thou, and fall on the priests. And Doeg the Edomite turned, and fell on the priests, and put to death that day eighty-five persons who wore the linen ephod. 19 And Nob, the city of the priests, he smote with the edge of the sword, both men and women, infants and sucklings, and oxen, and asses, and sheep, with the edge of the sword.

Commentary on 1 Samuel 22:6-19
(Read 1 Samuel 22:6-19)
See the nature of jealous malice and its pitiful arts. Saul looks upon all about him as his enemies, because they do not just say as he says. In Ahimelech's answer to Saul we have the language of conscious innocence. But what wickedness will not the evil spirit hurry men to when he gets the dominion! Saul alleges that which was utterly false and unproved. But the most bloody tyrants have found instruments of their cruelty as barbarous as themselves. Doeg, having murdered the priests, went to the city, Nob, and put all to the sword there. Nothing so vile but those may do it, who have provoked God to give them up to their hearts' lusts. Yet this was the accomplishment of the threatenings against the house of Eli. Though Saul was unrighteous in doing this, yet God was righteous in permitting it. No word of God shall fall to the ground.
