What happens to all the items that have holiness to them that are in the city of idol worshippers? Can the city be used for gardens and fields? Or can it never be rebuilt for any purpose? The city of Jericho can also never be rebuilt. The incident in sefer melachim where Chial rebuilt Jericho (or according to the gemara rebuilt a different city but called it Jericho) is quoted and analyzed and is related to Eliahu receiving the “key” for rain from God and bringing a huge drought. The masechet ends with a discussion of good and evil and their effects on the world.
