na'-dab (nadhabh, "noble"; Nadab):
(1) Aaron's first-born son (Ex 6:23; Nu 3:2; 26:60; 1Ch 6:3 (Heb 5:14); 24:1). He was permitted with Moses, Aaron, the 70 elders, and his brother Abihu to ascend Mt. Sinai and behold the God of Israel (Ex 24:1,9). He was associated with his father and brothers in the priestly office (Ex 28:1). Along with Abihu he was guilty of offering "strange fire," and both "died before Yahweh" (Le 10:1-2; Nu 3:4; 26:61). The nature of their offense is far from clear. The word rendered "strange" seems in this connection to mean no more than "unauthorized by the Law" (see zur, inBDB , and compare Ex 30:9). The proximity of the prohibition of wine to officiating priests (Le 10:8-9) has given rise to the erroneous suggestion of the Midrash that the offense of the brothers was drunkenness.
(2) A descendant of Jerahmeel (1Ch 2:28,30).
(3) A Gibeonite (1Ch 8:30).
(4) Son of Jeroboam I and after him for two years king of Israel (1Ki 14:20; 15:25). While Nadab was investing Gibbethon, a Philistine stronghold, Baasha, who probably was an officer in the army, as throne-robbers usually were, conspired against him, slew him and seized the throne (1Ki 15:27-31). With the assassination of Nadab the dynasty of Jeroboam was extirpated, as foretold by the prophet Ahijah (1Ki 14:1-31). This event is typical of the entire history of the Northern Kingdom, characterized by revolutions and counter-revolutions.
