Subsequently, (Leviticus 10:1) Nadab and his brother were struck dead before the sanctuary by fire from the Lord.

liberal, generous. (1.) The eldest of Aaron's four sons (Ex. 6:23; Num. 3:2). He with his brothers and their father were consecrated as priests of Jehovah (Ex. 28:1). He afterwards perished with Abihu for the sin of offering strange fire on the altar of burnt-offering (Lev. 10:1,2; Num. 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 (Josh. 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 Chr. 2:28, 30).
