2 Peter 2:4-5

4For God did not spare even the angels who sinned. He threw them into hell, in gloomy pits of darkness, where they are being held until the day of judgment.

5And 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.
