And the king said to Doeg, "You turn and kill the priests!" So Doeg the Edomite turned and struck the priests, and killed on that day eighty-five men who wore a linen ephod. Also Nob, the city of the priests, he struck with the edge of the sword, both men and women, children and nursing infants, oxen and donkeys and sheep—with the edge of the sword. 1 Samuel 22:18-19

Doeg was a Edomite in King Saul’s employ. He happened to witness the High Priest, Ahimelek giving aid to David as David fled from Saul.

As Saul pursued David, he learned about Ahimelek’s kindness to David and ordered his men to kill the priests for “siding with David.” They weren’t “siding with David against Saul. They had no knowledge of Saul’s murderous intentions regarding David. They knew that David was one of Saul’s men—who happened to also be Saul’s son-in-law. They were simply doing what anyone would have assumed was the right thing.

Because Saul’s senses were twisted by his jealousy against David, he sinfully ordered the execution of the priests, including Ahimelek, the High Priest.

Saul’s men refused to obey the order. But Doeg, not being Jewish and therefore having no respect for the priests, carried out Saul’s wickedly lethal order. Not content merely to kill the priests, he killed men, women, children and even livestock. Three points:

Jealous hatred pollutes good judgment, as it did with Saul.
Non-believers, like Doeg, seldom have a shred of respect for any aspect of the true religion.
Jews and Gentiles alike crucified Jesus, our Great High Priest. But unlike the people of Nob who died, we who are in Christ live because He died and then rose for us.
