Abihu was the second son of Aaron. He was cosecrated a priest along with his brothers Nadab, Eleazar, and Ithamar to minister at the Tabernacle (Ex. 28:1). But later, Abihu and Nadab were guilty of offering "profane fire before the Lord, such as He had not authorized." Both Abihu and Nadab died when "Fire came forth from the Lord's presence and consumed them." (Lev. 10:1-2).
