John Wesley on Job 22:20

Because - Because when wicked men are destroyed, they are preserved. He should have said their substance; but he changes the person, and saith, our substance; either as including himself in the member of righteous persons, and thereby intimating that he pleaded the common cause of all such, while Job pleaded the cause of the wicked, or because he would hereby thankfully acknowledge some eminent and particular preservation given to him amongst other righteous men. Remnant - All that was left undestroyed in the general calamity. Fire - Sodom and Gomorrah. As if he had said, thou mayest find here and there an instance, of a wicked man dying in peace. But what is that to the two great instances of the final perdition of ungodly men, the drowning the whole world, and the burning of Sodom and Gomorrah.
