Leviticus 10:6-7

King James Version

⁶ And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Uncover not your heads, neither rend your clothes; lest ye die, and lest wrath come upon all the people: 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 tabernacle of the congregation, lest ye die: for the anointing oil of the Lord is upon you. And they did according to the word of Moses.
