The article by Ronny Reich and Eli Shukron (“Light at the End of the Tunnel—Warren’s Shaft Theory of David’s Conquest Shattered”) on ancient Jerusalem’s water system promises to be one of the most carefully read and widely cited articles we have ever published—because of its implications for King David’s conquest of Jerusalem. Yet the authors do not pursue those implications. As they say in the last paragraph of their article, “Whether any part of this water system may be associated with the tsinnor referred to in the Bible, we leave to others.”
