Amorah (Gomorrah) was one of the five Cities of the Plain in the Jordan Valley (along with Sodom, Admah, Zeboiim, and Zoar). Together with Sodom, Gomorrah became the paradigmatic example of divine judgment on extreme wickedness. The cities were destroyed by 'sulfur and fire from the LORD out of the heavens' (Genesis 19:24) — a catastrophic event that left an indelible mark on Israel's religious memory.
Gomorrah's theological function throughout Scripture is as a warning archetype. The prophets repeatedly invoke it as shorthand for extreme wickedness deserving severe judgment (Isaiah 1:9-10; Jeremiah 23:14; Amos 4:11). In the New Testament, 2 Peter 2:6 says God 'condemned the cities of Sodom and Gomorrah by burning them to ashes, and made them an example of what is going to happen to the ungodly.' Yet even in judgment there is hope: the rescue of Lot demonstrates God's mercy for the righteous within, and Jesus' words in Matthew 10:15 suggest Sodom and Gomorrah's judgment will be lighter than that of cities rejecting the Gospel.
