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.
