Then Moses said unto Aaron, This is it that the LORD spake, saying, I will be {b} sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.

(b) I will punish them that serve me in other ways than I have commanded, not sparing the chief, that the people may fear and praise my judgments.

Wesley's Notes

10:3 The Lord spake - Though the words be not recorded in scripture, where only the heads of discourses are contained, yet it is probable they were uttered by Moses in God's name. Howsoever the sense of them is in many places. I will be sanctified - This may note, either, their duty to sanctify God, to demean themselves with such care, and reverence, and watchfulness, as becomes the holiness of the God whom they serve; whence he leaves them to gather the justice of the present judgment. Or, God's purpose to sanctify himself, to manifest himself to be an holy and righteous God by his severe and impartial punishment of all transgressors, how near soever they are to him. That come nigh me - Who draw near to me, or to the place where I dwell, and are admitted into the holy place, whence others are shut out. It is a description of the priests. I will be glorified - As they have sinned publickly and scandalously, so I will vindicate my honour in a public and exemplary manner, that all men may learn to give me the glory of my holiness by an exact conformity to my laws. And Aaron held his peace - In acknowledgment of God's justice and submission to it. He murmured not, nor replied against God.

Jamieson-Fausset-Brown Bible Commentary

3. Moses said . This is it that the Lord spoke . I will be sanctified in them that come nigh me-"They that come nigh me," points, in this passage, directly to the priests; and they had received repeated and solemn warnings as to the cautious and reverent manner of their approach into the divine presence (Ex 19:22; 29:44; Le 8:35).

Aaron held his peace-The loss of two sons in so sudden and awful a manner was a calamity overwhelming to parental feelings. But the pious priest indulged in no vehement ebullition of complaint and gave vent to no murmur of discontent, but submitted in silent resignation to what he saw was "the righteous judgment of God" [Ro 2:5].

Matthew Henry's Concise Commentary

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.
