Leviticus 10:6

And Moses said to Aaron, and Eleazar and Ithamar his sons that were left, You⌃ shall not make bare your heads, and you⌃ shall not tear your garments; that you⌃ die not, and [so] there should be wrath on all the congregation: but your brethren, [even] all the house of Israel, shall lament for the burning, with which they were burnt by the Lord.
