'Sodom and Gomorrah' in the Bible

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

Any place that does not welcome you or listen to you, when you leave there, shake the dust off the soles of your feet as a testimony against them [breaking all ties with them because they rejected My message].”

And, as Isaiah had said before, If the Lord of armies had not given us a seed, we would have been like Sodom and Gomorrah.

and turning the cities of Sodom and Gomorrah into ashes condemned them with an overthrow, having made them an example unto those that should live ungodly;

Even as Sodom and Gomorrah, and the cities about them, having in like manner with these given themselves over to fornication and gone after strange flesh, are set forth as an example, suffering the punishment of eternal fire.
