Nadab and Abihu, the sons of Aaron, who ministered in the holy office of priesthood, partook freely of wine and, as was their usual custom, went in to minister before the Lord. The priests who burned incense before the Lord were required to use the fire of God’s kindling, which burned day and night and was never extinguished. God gave explicit directions how every part of His service should be conducted, that all connected with His sacred worship might be in accordance with His holy character. And any deviation from the express directions of God in connection with His holy service was punishable with death. (Con 80.1) MC VC
