6 Moses then said to Aaron and his remaining sons, Eleazar and Ithamar, "No mourning rituals for you - unkempt hair, torn clothes - or you'll also die and God will be angry with the whole congregation. Your relatives - all the People of Israel, in fact - will do the mourning over those God has destroyed by fire.
Matthew Henry's Commentary on Leviticus 10:6
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.
