'Ungodly' in the Bible

and did not spare the ancient world, but preserved Noah, a preacher of righteousness, with seven others, when He brought a flood upon the world of the ungodly;

and if He condemned the cities of Sodom and Gomorrah to destruction by reducing them to ashes, having made them an example to those who would live ungodly lives thereafter;

But by His word the present heavens and earth are being reserved for fire, kept for the day of judgment and destruction of ungodly men.
