Psalm 119:78

Let the proud be ashamed
The same persons he before speaks of as accursed, who had him in derision, and forged a lie against him. Here he prays that they might be ashamed of their scoffs and jeers, of their lies and calumnies, the evils and injuries they had done him; that they might be brought to a sense of them, and repentance for them; when they would be ashamed of them in the best manner: or that they might be disappointed of their ends, in what they had done, and so be confounded and ashamed, as men are when they cannot gain their point; or be brought to shame and confusion eternally;

for they dealt perversely with me without a cause;
or, "they perverted me [with] falsehood" ^F23; that is, they endeavoured to pervert him with lies and falsehood, and lead him out of the right way; or they attempted, by their lies and calumnies, to make him out to be a perverse and wicked man, and pronounced and condemned him as such, without any foundation or just cause for it;

[but] I will meditate in thy precepts;
he was determined, in the strength of grace, that those ill usages should not take off his thoughts from religious things, or divert him from his duty to his God: none of these things moved him; he still went on in the ways of God, in his worship and service, as Daniel did, when in like circumstances.
