Leviticus 10:2-9

²And there went out a fire from before the Lord, and consumed them, and they died before the Lord.

³Then said Moses unto Aaron, This is what the Lord hath spoken, saying, On those who are near unto me will I be sanctified, and before all the people will I be glorified: and Aaron held his peace.

⁴And Moses called unto Mishael and Elzaphan, the sons of 'Uzziel, the uncle of Aaron, and said unto them, Come near, carry your brethren from before the sanctuary to without the camp.

⁵And they came near, and carried them in their coats to without the camp; as Moses had spoken.

⁶And Moses said unto Aaron, and unto Elazar and unto Ithamar, his sons, The hair of your head you shall not let grow long, and your garments you shall not rend, that ye die not, and that he be not wroth upon the whole congregation; but your brethren, the whole house of Israel, may bewail the burning which the Lord hath kindled.

⁷And from the door of the tabernacle of the congregation shall ye not go out, lest ye die; for the anointing oil of the Lord is upon you; and they did according to the word of Moses.

⁸And the Lord spoke unto Aaron, saying,

⁹Wine or strong drink shalt thou not drink, neither thou, nor thy sons with thee, when ye go in unto the tabernacle of the congregation, lest ye die: it shall be a statute for ever throughout your generations.
