6 And Moses said to Aaron and to his sons Eleazar and Ithamar, "Do not dishevel your hair, and do not tear your vestments, or you will die and wrath will strike all the congregation; but your kindred, the whole house of Israel, may mourn the burning that the Lord has sent. 7 You shall not go outside the entrance of the tent of meeting, or you will die; for the anointing oil of the Lord is on you." And they did as Moses had ordered.

Commentary on Leviticus 10:3-7
(Read Leviticus 10:3-7)
The most quieting considerations under affliction are fetched from the word of God. What was it that God spake? Though Aaron's heart must have been filled with anguish and dismay, yet with silent submission he revered the justice of the stroke. When God corrects us or ours for sin, it is our duty to accept the punishment, and say, It is the Lord, let him do what seemeth him good. Whenever we worship God, we come nigh unto him, as spiritual priests. This ought to make us very serious in all acts of devotion. It concerns us all, when we come nigh to God, to do every religious exercise, as those who believe that the God with whom we have to do, is a holy God. He will take vengeance on those that profane his sacred name by trifling with him.
