2 Say we, therefore, ourselves also: “Hearken, O God, to my prayer, while I am troubled; from fear of the enemy deliver my soul”. Enemies have raged against the Martyrs: for what was that voice of Christ's Body praying? For this it was praying, to be delivered from enemies, and that enemies might not have power to slay them. Were they not therefore hearkened to, because they were slain; and has God forsaken His servants of a contrite heart, and despised men hoping in Him? Far be it. For “who has called upon God, and has been forsaken; who has hoped in Him, and has been deserted by Him?” They were hearkened to therefore, and they were slain; and yet from enemies they were delivered. Others being afraid gave consent, and lived, and yet the same by enemies were swallowed up. The slain were delivered, the living were swallowed up. Thence is also that voice of thanksgiving, “Perchance alive they would have swallowed us up.”...Therefore for this prays the voice of the Martyrs, “From fear of the enemy deliver my soul:” not so that the enemy may not slay me, but that I may not fear an enemy slaying. For that to be fulfilled in the Psalm the servant prays, which but now in the Gospel the Lord was commanding. What but now was the Lord commanding? “Fear not them that kill the body, but the soul are not able to kill; but Him rather fear ye, that has power to kill both body and soul in the hell of fire.” And He repeated, “Yea, I say unto you, fear Him.” Who are they that kill the body? Enemies. What was the Lord commanding? That they should not be feared. Be prayer offered, therefore, that He may grant what He has commanded. “From fear of the enemy deliver my soul.” Deliver me from fear of the enemy, and make me submit to the fear of You. I would not fear him that kills the body, but I would fear Him that has power to kill both body and soul in the hell of fire. For not from fear would I be free: but from fear of the enemy being free, under fear of the Lord a servant.
3. “You have protected me from the gathering together of malignants, and from the multitude of men working iniquity”. Now upon Himself our Head let us look. Like things many Martyrs have suffered: but nothing does shine out so brightly as the Head of Martyrs; in Him rather let us behold what they have gone through. Protected He was from the multitude of malignants, God protecting Himself, the Son Himself and the Manhood which He was carrying protecting His flesh: because Son of Man He is, and Son of God He is; Son of God because of the form of God, Son of Man because of the form of a servant: having in His power to lay down His life: and to take it again. To Him what could enemies do? They killed body, soul they killed not. Observe. Too little therefore it were for the Lord to exhort the Martyrs with word, unless He had enforced it by example. You know what a gathering together there was of malignant Jews, and what a multitude there was of men working iniquity. What iniquity? That wherewith they willed to kill the Lord Jesus Christ. “So many good works,” He says, “I have shown to you, for which of these will you to kill Me?” He endured all their infirm, He healed all their sick, He preached the Kingdom of Heaven, He held not His peace at their vices, so that these same should have been displeasing to them, rather than the Physician by whom they were being made whole: for all these His remedies being ungrateful, like men delirious in high fever raving at the physician, they devised the plan of destroying Him that had come to heal them; as though therein they would prove whether He were indeed a man, that could die, or were somewhat above men, and would not suffer Himself to die. The word of these same men we perceive in the wisdom of Solomon: “with death most vile,” say they, “let us condemn Him; let us question Him, for there will be regard in the discourses of Him; for if truly Son of God He is, let Him deliver Him.” Let us see therefore what was done.
4. “For they have whet like a sword their tongues”. Which says another Psalm also, “Sons of men; their teeth are arms and arrows, and their tongue is a sharp sword.” Let not the Jews say, we have not killed Christ. For to this end they gave Him to Pilate the judge, in order that they themselves might seem as it were guiltless of His death....But if he is guilty because he did it though unwillingly, are they innocent who compelled him to do it? By no means. But he gave sentence against Him, and commanded Him to be crucified: and in a manner himself killed Him; ye also, O you Jews, killed Him. Whence did ye kill Him? With the sword of the tongue: for you did whet your tongues. And when did ye smite, except when you cried out, “Crucify, Crucify”?
