'Sodom and Gomorrah' in the Bible

Verily I say to you, It shall be more tolerable for the land of Sodom and Gomorrah, in the day of judgment, than for that city.

and if, turning the cities of Sodom and Gomorrah into ashes, he condemned them with an overthrow, making them an example to those who should afterward live in an ungodly manner,

So Sodom and Gomorrah, and the cities which were about them, in like manner giving themselves over to lewdness, and following after other flesh, are set forth as an example, suffering the punishment of eternal fire.
