Victorinus of Pettau

"And out of His mouth was issuing a sharp two-edged sword." By the twice-sharpened sword going forth out of His mouth is shown, that it is He Himself who has both now declared the word of the Gospel, and previously by Moses declared the knowledge of the law to the whole world. But because from the same word, as well of the New as of the Old Testament, He will assert Himself upon the whole human race, therefore He is spoken of as two-edged. For the sword arms the soldier, the sword slays the enemy, the sword punishes the deserter. And that He might show to the apostles that He was announcing judgment, He says: "I came not to send peace, but a sword." And after He had completed His parables, He says to them: "Have ye understood all these things? And they said, We have. And He added, Therefore is every scribe instructed in the kingdom of God like unto a man that is a father of a family, bringing forth from his treasure things new and old," -the new, the evangelical words of the apostles; the old, the precepts of the law and the prophets: and He testified that these proceeded out of His mouth. Moreover, He also says to Peter: "Go thou to the sea, and cast a hook, and take up the fish that shall first come up; and having opened its mouth, thou shalt find a stater (that is, two denarii), and thou shalt give it for me and for thee." And similarly David says by the Spirit: "God spake once, twice I have heard the same." Because God once decreed from the beginning what shall be even to the end. Finally, as He Himself is the Judge appointed by the Father. on account of His assumption of humanity, wishing to show that men shall be judged by the word that He had declared, He says: "Think ye that I will judge you at the last day? Nay, but the word," says He, "which I have spoken unto you, that shall judge you in the last day." And Paul, speaking of Antichrist to the Thessalonians, says: "Whom the Lord Jesus will slay by the breath of His mouth." And Isaiah says: "By the breath of His lips He shall slay the wicked." This, therefore, is the two-edged sword issuing out of His mouth.
