The Arabic word '''Tsabians''' (Σοβιαΐ) refers to a religious group described as Mithrean Messianic Noahites. The original Mithreans were called [[Mages]] while the Arabic word Tsabi is closer to Sebomenoi (Σεβομενοι), the Greek word for Noahites which was Tarsak (pl. Tarsakan) in Persian. The first Mages to become Tsabis are described in Chapter 2 of the Gospel of Matthew.
The Arabic term Tsabi (Mithrean Messianic Noahites) or its Greek plural Sobiai also referred to [[Ekhasai]]'s "Hearers" (ismai'i) or the Manicheans' Uninitiated Audience which has caused all Sobiai to be often simply (and inaccurately) referred to as Manicheans even though they were not aware of the "Great Secret" of Mani's Gnosticism. The Persian word for such Tsabis was [[Tazig|Tazig, (pl. Tazigan)]] (perhaps derived from Tarsak) while the Soghdian word was [[Nighòshagàn]].
Tsabians are described in Arabic sources as being between Karaite-Judaizers, Nazarenes and Mithrean people of Noah who awaited their "Persian Messenger". They said la ilaha il allah, used to face a specific direction (perhaps south) to pray the Liturgy of Hours and fasted for the Nativity Fast every year.
