Charles H. Spurgeon on Psalms 52:6

The righteous also shall see, etc. That is, to use the apt words of Gejerus, "This shall not be a secret judgment, or known only to a few, but common fame shall spread abroad throughout the kingdom, or city, the notable punishments of the ungodly. The righteous also shall not pass by such an event with indifference, but with earnest eyes shall contemplate it, "etc. I add, and hence shall they take joy, and turn it to their own use, to the greater fearing of God... The righteous, upon whose destruction the ungodly man was intent, shall survive and spend their lives safe in the favour of God; they shall see with attentive mind, they shall consider; nor, as worldlings are accustomed, shall they pass it by without reflection or improvement, they shall see and fear, namely, God the just judge; and instructed in his judgment by this instance, they shall be the more careful to abstain from all designs and crimes of this kind. Hermann Venema.
