1 Samuel 22:21 (KJV)

And the king said, Thou shalt surely die, Ahimelech, thou, and all thy father's house.

And the king said unto the footmen that stood about him, Turn, and slay the priests of the LORD: because their hand also is with David, and because they knew when he fled, and did not shew it to me. But the servants of the king would not put forth their hand to fall upon the priests of the LORD.

And the king said to Doeg, Turn thou, and fall upon the priests. And Doeg the Edomite turned, and he fell upon the priests, and slew on that day fourscore and five persons that did wear a linen ephod.

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

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

And David said unto Abiathar, I knew it that day, when Doeg the Edomite was there, that he would surely tell Saul: I have occasioned the death of all the persons of thy father's house.

Abide thou with me, fear not: for he that seeketh my life seeketh thy life: but with me thou shalt be in safeguard.
