Leviticus 10:6 AMPC

[6] And Moses said to Aaron and Eleazar and Ithamar, his sons [the father and brothers of the two priests whom God had slain for offering false fire], Do not uncover your heads or let your hair go loose or tear your clothes, lest you die [also] and lest God's wrath should come upon all the congregation; but let your brethren, the whole house of Israel, bewail the burning which the Lord has kindled.
