Charles H. Spurgeon on Psalms 35:4

"Let them be confounded and put to shame that seek after my soul." There is nothing malicious here, the slandered man simply craves for justice, and the petition is natural and justifiable. Guided by God's good spirit the Psalmist foretells the everlasting confusion of all the haters of the righteous. Shameful disappointment shall be the portion of the enemies of the gospel, nor would the most tender-hearted Christian have it otherwise: viewing sinners as men, we love them and seek their good, but regarding them as enemies of God, we cannot think of them with anything but detestation, and a loyal desire for the confusion of their devices. No loyal subject can wish well to rebels. Squeamish sentimentality may object to the strong language here used, but in their hearts all good men wish confusion to mischief-makers.
