Nadav and Avihu

(1) And Nadab and Abihu, the sons of Aaron, took each of them his censer, and put fire therein, and laid incense thereon, and offered strange fire before the LORD, which He had not commanded them. (2) And there came forth fire from before the LORD, and devoured them, and they died before the LORD. (3) Then Moses said unto Aaron: ‘This is it that the LORD spoke, saying: Through them that are nigh unto Me I will be sanctified, and before all the people I will be glorified.’ And Aaron held his peace....(6) And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons: ‘Let not the hair of your heads go loose, neither tend your clothes, that ye die not, and that He be not wroth with all the congregation; but let your brethren, the whole house of Israel, bewail the burning which the LORD hath kindled. (7) And ye shall not go out from the door of the tent of meeting, lest ye die; for the anointing oil of the LORD is upon you.’ And they did according to the word of Moses. (8) And the LORD spoke unto Aaron, saying: (9) ’Drink no wine nor strong drink, thou, nor thy sons with thee, when ye go into the tent of meeting, that ye die not; it shall be a statute forever throughout your generations. (10) And that ye may put difference between the holy and the common, and between the unclean and the clean; (11) and that ye may teach the children of Israel all the statutes which the LORD hath spoken unto them by the hand of Moses.’
