Psalms 52:2

2.Thy tongue reckons up mischiefs David is not to be considered as here venting a flood of reproaches against his adversary, as many who have been unjustly injured are in the habit of doing, merely to gratify a feeling of revenge. He brings these charges against him in the sight of God, with a view to encourage himself in the hopefulness of his own cause: for it is plain that the farther our enemies proceed in the practice of iniquity, they proportionally provoke the anger of the Lord, and are nearer to that destruction which must issue in our deliverance. His object, therefore, is not to blacken the character of Doeg in the estimation of the world, but rather to set before his own eyes the divine punishment which the flagrant offenses he specifies were certain to draw down upon his head. Amongst these he singles out, as more especially worthy of reprobation, the hidden treachery with which he had been chargeable in accomplishing the destruction of the priesthood. Adverting to his secret and malicious information, he likens his tongue to a sharp razor, as elsewhere, Psalms 120:4, the tongues of the wicked are compared to “sharp arrows.” It is added, working deceitfully, which words are considered by some as referring to the razor which cuts subtilely, and not with an open wound like a sword; but perhaps they may be construed with more propriety as applying to the tongue, (276) although there can be no doubt of the reason of the comparison.
