Weihrauchstraße
The town's ruins, called in Arabic Khirbet Ruheibeh, are located in the Wadi er-Ruheibeh area, where Isaac's well was (latitude 31° 1′ N, longitude 34° 33′ E). This was a thriving city in Byzantine times. In Israel today it is called "Rehovot ba-Negev" (Rehovot-in-the-Negev). It was apparently founded in the first century AD by the Nabateans. It grew to more than 10,000 people by the fifth century, thanks to its being on the Incense Route.
