Nebaioth

Height.

  1. Ishmael's eldest son (Gen. 25:13), and the prince of an Israelitish tribe (25:16). He had a sister, Mahalath, who was one of Esau's wives (Gen. 28:9, 36:3).
  2. The name of the Ishmaelite tribe descended from the above (Gen. 25:13, 18). The "rams of Nebaioth" (Isa. 60:7) are the gifts which these wandering tribes of the desert would consecrate to God.
