Leviticus 10:6-7

⁶ And Moses saith unto Aaron, and to Eleazar, and to Ithamar his sons, 'Your heads ye do not uncover, and your garments ye do not rend, that ye die not, and on all the company He be wroth; as to your brethren, the whole house of Israel, they bewail the burning which Jehovah hath kindled; ⁷ and from the opening of the tent of meeting ye do not go out, lest ye die, for the anointing oil of Jehovah 'is' upon you;' and they do according to the word of Moses.
