verse 13-20
Verse 13. Let his posterity be cut off; and in the generation following let their name be blotted out. Both from existence and from memory let them pass away till none shall know that such a vile brood ever existed. Who wishes to see the family of Domitian or Julian continued upon earth? Who would mourn if the race of Tom Paine or of Voltaire should come to an utter end? It would be undesirable that the sons of the utterly villainous and bloodthirsty should rise to honour, and if they did they would only revive the memory of their father's sins.
Verse 14. This verse is, perhaps, the most terrible of all, but yet as a matter of fact children do procure punishment upon their parents' sins, and are often themselves the means of such punishment. A bad son brings to mind his father's bad points of character; people say, "Ah, he is like the old man. He takes after his father." A mother's sins also will be sure to be called to mind if her daughter becomes grossly wicked. "Ah", they will say, "there is little wonder, when you consider what her mother was." These are matters of everyday occurrence. We cannot, however, pretend to explain the righteousness of this malediction, though we fully believe in it. We leave it till our heavenly Father is pleased to give us further instruction. Yet, as a man's faults are often learned from his parents, it is not unjust that his consequent crimes should recoil upon him.
Verse 15. Again, he wishes that his father's sins may follow up the transgressor and assist to fill the measure of his own iniquities, so that for the whole accumulated load the family may be smitten with utter extinction. A king might justly wish for such an end to fall upon an incorrigible brood of rebels; and of persecutors, continuing in the same mind, the saints might well pray for their extinction; but the passage is dark; and we must leave it so. It must be right or it would not be here, but how we cannot see. Why should we expect to understand all things? Perhaps it is more for our benefit to exercise humility, and reverently worship God over a hard text, than it would be to comprehend all mysteries.
Verse 16. Because that he remembered not to shew mercy. Because he had no memory to show mercy the Judge of all will have a strong memory of his sins. So little mercy had he ever shown that he had forgotten how to do it, he was without common humanity, devoid of compassion, and therefore only worthy to be dealt with after the bare rule of justice. But persecuted the poor and needy man. He looked on poor men as a nuisance upon the earth, he ground their faces, oppressed them in their wages, and treated them as the mire of the streets. Should he not be punished, and in his turn laid low? All who know him are indignant at his brutalities, and will glory to see him overthrown. That he might even slay the broken in heart. He had malice in his heart towards one who was already sufficiently sorrowful, whom it was a superfluity of malignity to attack. Yet no grief excited sympathy in him, no poverty ever moved him to relent. No, he would kill the heart broken and rob their orphans of their patrimony. To him groans were music, and tears were wine, and drops of blood precious rubies. Would any man spare such a monster? Will it not be serving the ends of humanity if we wish him gone, gone to the throne of God to receive his reward? If he will turn and repent, well: but if not, such a up as tree ought to be felled and cast into the fire. As men kill mad dogs if they can, and justly too, so may we lawfully wish that cruel oppressors of the poor were removed from their place and office, and, as an example to others, made to smart for their barbarities.
Verse 17. As he loved cursing, so let it come unto him. Deep down in every man's soul the justice of the
lex talionis is established. Retaliation, not for private revenge, but as a measure of public justice, is demanded by the psalmist and deserved by the crime. Surely the malicious man cannot complain if he is judged by his own rule, and has his corn measured with his own bushel. Let him have what he loved. They are his own chickens, and they ought to come home to roost. He made the bed, let him lie on it himself. As he brewed, so let him drink. So all men say as a matter of justice, and though the higher law of love overrides all personal anger, yet as against the base characters here described even Christian love would not wish to see the sentence mitigated. As he delighted not in blessing, so let it be far from him. He felt no joy in any man's good, nor would he lift a hand to do another a service, rather did he frown and fret when another prospered or mirth was heard under his window; what, then, can we wish him? Blessing was wasted on him, he hated those who gently sought to lead him to a better mind; even the blessings of providence he received with murmurs and repinings, he wished for famine to raise the price of his corn, and for war to increase his trade. Evil was good to him, and good he counted evil. If he could have blasted every field of corn in the world he would have done so if he could have turned a penny by it, or if he could thereby have injured the good man whom he hated from his very soul. What can we wish for him? He hunts after evil, he hates good; he lays himself out to ruin the godly whom God has blessed, he is the devil's friend, and as fiendish as his patron; should things go well with such a being? Shall we "wish him good luck in the name of the Lord?" To invoke blessings on such a man would be to participate in his wickedness, therefore let blessing be far from him, so long as he continues what he now is.
Verses 18-19. He was so openly in the habit of wishing ill to others that he seemed to wear robes of cursing, therefore let it be as his raiment girded and belted about him, yea, let it enter as water into his bowels, and search the very marrow of his bones like a penetrating oil. It is but common justice that he should receive a return for his malice, and receive it in kind, too.
Verse 20. This is the summing up of the entire imprecation, and fixes it upon the persons who had so maliciously assailed the inoffensive man of God. David was a man of gentle mould, and remarkably free from the spirit of revenge, and therefore we may here conceive him to be speaking as a judge or as a representative man, in whose person great principles needed to be vindicated and great injuries redressed. Thousands of God's people are perplexed with this psalm, and we fear we have contributed very little towards their enlightenment, and perhaps the notes we have gathered from others, since they display such a variety of view, may only increase the difficulty. What then? Is it not good for us sometimes to be made to feel that we are not yet able to understand all the word and mind of God? A thorough bewilderment, so long as it does not stagger our faith, may be useful to us by confounding our pride, arousing our faculties, and leading us to cry, "What I know not teach thou me."
