John Calvin Commentary 2 Peter 2:8

"(for that righteous man dwelling among them, in seeing and hearing, vexed [his] righteous soul from day to day with [their] lawless deeds):" — 2 Peter 2:8 (ASV)

In seeing and hearing. The common explanation is that Lot was just in his eyes and ears, because all his senses abhorred the crimes of Sodom. However, another view may be taken of his seeing and hearing, understanding it to mean that when the just man lived among the Sodomites, he tormented his soul by seeing and hearing; for we know that he was constrained to see and hear many things that greatly vexed his mind. The purport of what is said, then, is that though the holy man was surrounded with every kind of monstrous wickedness, he yet never turned aside from his upright course.

But Peter expresses more than before, that is, that just Lot underwent voluntary sorrows. As it is right that all the godly should feel no small grief when they see the world rushing into every kind of evil, so it is all the more necessary that they should groan for their own sins. And Peter expressly mentioned this, lest, when impiety everywhere prevails, we should be captivated and inebriated by the allurements of vices and perish together with others, but rather that we should prefer this grief, blessed by the Lord, to all the pleasures of the world.
