Leviticus 10:3

And Moses said unto Aaron,.... Upon this awful occasion, and in order to quiet and humble him under the mighty hand of God:this [is it] that the Lord spoke, saying; but when he spoke it, and where it is said and recorded, is not so very clear; it might have been said, and yet not recorded, or the substance of it may be recorded, though not in the express words here delivered; it may refer, as some think, to Ex 19:22 or else to Ex 29:43 which seems to come nearest to what follows, so Jarchi:I will be sanctified in them that come nigh me; in the priests that drew nigh to him, and offered sacrifice and burnt incense to him; by these he expected to be sanctified, not to be made holy, but to be declared to be so, and obeyed and worshipped as such; as he is, when his commands and ordinances are observed, as he would have them be, in faith and fear, which were not done by these sons of Aaron; and therefore the Lord, by the punishment he inflicted, showed himself to be an holy, righteous, and jealous God:and before all the people I will be glorified; as he is when he is believed and trusted in; when his worship is carried on in his own house, according to his will; when his ordinances are kept as they were delivered, and when he is reverenced in the assembly of his saints; all which were wanting in this case.
