Nebaioth was Ishmael’s firstborn son and the name of the pastoral tribe descended from him. The tribe was associated with the desert and with flocks, especially rams. Nebaioth was also connected by family tradition with Mahalath, a wife of Esau.
Isaiah speaks of the rams of Nebaioth as gifts brought to God and as sacrificial offerings connected with the ideal Zion. Nebaioth is associated with Kedar in the prophetic description.
The tribe had a conspicuous place among the northern Arabs and appears frequently with Kedar in Assyrian inscriptions. Its identification with the Nabateans has been proposed and widely accepted by some, but the supplied material notes linguistic difficulties and does not regard the identification as certain.
