'Example' in the Bible

and if He reduced the cities of Sodom and Gomorrah to ashes and condemned them to ruin, making them an example to those who were going to be ungodly;

They are an example of that true saying, The dog has gone back to the food it had put out, and the pig which had been washed to its rolling in the dirty earth.

Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.
