(1.) The eldest of Aaron's four sons (Exodus 6:23; Numbers 3:2). He with his brothers and their father were consecrated as priests of Jehovah (Exodus 28:1). He afterwards perished with Abihu for the sin of offering strange fire on the altar of burnt-offering (Leviticus 10:1, 2; Numbers 3:4; 26:60).
(2.) The son and successor of Jeroboam, the king of Israel (1 Kings 14:20). While engaged with all Israel in laying siege to Gibbethon, a town of southern Dan (Joshua 19:44), a conspiracy broke out in his army, and he was slain by Baasha (1 Kings 15:25-28), after a reign of two years (B.C. 955-953). The assassination of Nadab was followed by that of his whole house, and thus this great Ephraimite family became extinct (1 Kings 15:29).
(3.) One of the sons of Shammai in the tribe of Judah (1 Chronicles 2:28, 30).
