2 Chronicles 20:1-2

Later the Moabites, Ammonites, and some Meunites came to start a war with Jehoshaphat. Messengers came and told Jehoshaphat, “A large army is coming against you from Edom, from the other side of the Dead Sea. They are already in Hazazon Tamar!” (Hazazon Tamar is also called En Gedi.)
