The superscription of the fifty-second Psalm bears--"Maschil of David; when Doeg the Edomite came and told Saul, David is come to the house of Ahimelech." There is not much in this title to recommend it, as the information that was given by Doeg to Saul is not stated accurately. We might have expected, too, that if Doeg was alone in the Psalmist's eye, the atrocious slaughter of the priests would have had a share of reprobation, as well as the sharp, calumnious, mischievous tongue which is the chief object of denunciation. And though Doeg, as the chief of Saul's bondmen, might be a rich man, that position would hardly have entitled him to be called a mighty man, nor to assume the swaggering tone of independence here ascribed to him. Whoever was really the object of denunciation in this psalm, seems however to have belonged to the same class with Doeg, in respect of his wicked tongue and love of mischief. It is indeed a wretched character that is delineated: the Psalmist's enemy is at once mischievous and mighty; and not only is he mischievous, but he boasts himself in it. He is shameless and without conscience, bent on doing all the evil that he can. Let him only have a chance of bringing a railing accusation against God's servants, and he does it with delight. But his conduct is senseless as it is wicked. God is unchangeably good, and His goodness is a sure defence to His servants against all the calumnious devices of the greatest and strongest of men. It is the tongue of this evil man that is his instrument of mischief. It is utterly unscrupulous, sharp as a razor, cunning, devouring. A liar is a serious enemy, one who is utterly unprincipled, clever withal, and who trains himself with great skill to do mischief with his tongue. It is painful to be at the mercy of a calumniator who does not launch against you a clumsy and incredible calumny, but one that has an element of probability in it, only fearfully distorted. Especially when the calumniator is one that _deviseth_ mischief, who loves evil more than good, to whom truth is too tame to be cared for, who delights in falsehood because it is more piquant, more exciting. To those who have learned to regard it as the great business of life to spread light, order, peace, and joy, such men appear to be monsters, and indeed they are; but it is a painful experience to lie at their mercy.
