Psalms 64:4

"They have bended the bow, a bitter thing, in order that they may shoot in secret One unspotted" [Psalm 64:4]. The bow he calls lyings in wait. For he that with sword fights hand to hand, openly fights: he that shoots an arrow deceives, in order to strike. For the arrow smites, before it is foreseen to come to wound. But whom could the lyings in wait of the human heart escape? Would they escape our Lord Jesus Christ, who had no need that any one should bear witness to Him of man? "For Himself knew what was in man," [John 2:25] as the Evangelist testifies. Nevertheless, let us hear them, and look upon them in their doings as if the Lord knew not what they devise. The expression he used, "They have bended the bow," is the same as, "in secret:" as if they were deceiving by lyings in wait. For you know by what artifices they did this, how with money they bribed a disciple that clave to Him, in order that He might be betrayed to them, [Matthew 26:14-15] how they procured false witnesses; with what lyings in wait and artifices they wrought, "in order that they might shoot in secret One unspotted." Great iniquity! Behold from a secret place there comes an arrow, which strikes One unspotted, who had not even so much of spot as could be pierced with an arrow. A Lamb indeed He is unspotted, wholly unspotted, always unspotted; not one from whom spots have been removed but that has contracted not any spots. For He has made many unspotted by forgiving sins, being Himself unspotted by not having sins. "Suddenly they shall shoot Him, and shall not fear." O heart hardened, to wish to kill a Man that did raise the dead! "Suddenly:" that is, insidiously, as if unexpectedly, as if not foreseen. […]

But, (1.) Their tongues are their swords, flaming swords, two-edged swords, drawn swords, drawn in anger, with which they cut, and wound, and kill, the good name of their neighbours. The tongue is a little member, but, like the sword, it boasts great things, Jam. iii. It is a dangerous weapon.

By the spirit of prophecy he foretels their destruction, which would redound to the glory of God and the encouragement of his people,

That they may shoot in secret at the perfect. They lie in ambush, with bows ready bent to aim a coward's shaft at the upright man. Sincere and upright conduct will not secure us from the assaults of slander. The devil shot at our Lord himself, and we may rest assured he has a fiery dart in reserve for us; He was absolutely perfect, we are only so in a relative sense, hence in us there is fuel for fiery darts to kindle on.

Observe the meanness of malicious men; they will not accept fair combat, they shun the open field, and skulk in the bushes, lying in ambush against those who are not so acquainted with deceit as to suspect their treachery, and are to manly to imitate their despicable modes of warfare. Suddenly do they shoot at him, and fear not. To secrecy they add suddenness. They give their unsuspecting victim no chance of defending himself; they pounce on him like a wild beast leaping on its prey. They lay their plans so warily that they fear no detection. We have seen in daily life the arrow of calumny wounding its victim sorely; and yet we have not been able to discover the quarter from which the weapon was shot, nor to detect the hand which forged the arrowhead, or tinged it with the poison. Is it possible for justice to invent a punishment sufficiently severe to meet the case of the dastard who defiles my good name, and remains himself in concealment? An open liar is an angel compared with this demon. Vipers and cobras are harmless and amiable creatures compared with such a reptile. The devil himself might blush at being the father of so base an offspring.
