Jack Kelley: Tishbe was in Gilead (north western Jordan today) an area east of the Jordan River that was given to the Tribe of Manasseh in Joshua's day.
Wikipedia: 1 Kings 17:1 indicates that Elijah was from Tishbe in Gilead, which is a historical region located east of the Jordan River in present Jordan. The Jewish ancient historian Josephus supposed that Tishbe was in Gilead. The eastern half of the Israelite Tribe of Manasseh and, possibly also, the Tribe of Gad, have been in possession of Gilead; therefore Tishbe was probably in the territory of the eastern half of Manasseh, or possibly in that of Gad. According to Pfeiffer and Vos, it is located in the territory of Manasseh, in proximity to the wadi known from the Bible as Cherith, in present-day Jordan.
