What does the Bible say about Sodom and Gomorrah?

Sodom and Gomorrah are mentioned in the Bible as examples of divine judgment due to their extreme wickedness, particularly sexual immorality and pride. According to Jude 1:7, these cities 'gave themselves over to fornication and went after strange flesh,' leading to their destruction by 'eternal fire.' This judgment serves as an example for others, illustrating the seriousness of defying God's moral laws and the dire consequences that follow. The account emphasizes the forfeiture of both temporal and eternal mercies as a result of ungratefulness and sin.
