Read 2 Peter 2:5 Using Other Translations
And spared not the old world, but saved Noah the eighth person, a preacher of righteousness, bringing in the flood upon the world of the ungodly;
if he did not spare the ancient world, but preserved Noah, a herald of righteousness, with seven others, when he brought a flood upon the world of the ungodly;
And God did not spare the ancient world—except for Noah and the seven others in his family. Noah warned the world of God’s righteous judgment. So God protected Noah when he destroyed the world of ungodly people with a vast flood.
