 The suggestion that they came from the Hejaz area is considered to be more convincing, as they share many deities with the ancient people there; "nbtw", the root consonant of the tribe's name, is found in the early Semitic languages of Hejaz.Similarities between late Nabataean Arabic dialect and the ones found in Mesopotamia during the Neo-Assyrian period, as well as a group with the name of "Nabatu" being listed by the Assyrians as one of several rebellious Arab tribes in the region, suggests a connection between the two.The Nabataeans might have originated from there and migrated west between the 6th and 4th centuries BC into northwestern Arabia and much of what is now modern-day Jordan.
