The firstborn son of Aaron the Priest. Nadab served as an anointed priest under his father until he offered "strange fire" before God with his younger brother Abihu (Leviticus 10:1; Numbers 3:4). When they offered this fire God sent forth a fire that utterly consumed them both. Before his death Nadab went with the seventy elders of Israel when they went with Moses and saw the God of Israel (Exodus 24:9-11). When Nadab was killed by God he had no children.
In Hebrew his name is נדב (pronounced: nah-dahv). His name basically means "generous."
