John Gill's Bible Commentary Ver. 1. And the Lord spake unto Moses, after the death of the two sons of Aaron , etc.] That is, either immediately after their death, and so this chapter would have stood in its natural order next to the tenth; or else after the above laws concerning uncleanness on various accounts were delivered out, designed to prevent the people entering into the tabernacle defiled, whereby they would have incurred the penalty of death; wherefore, as Aben Ezra observes, after the Lord had given cautions to the Israelites, that they might not die, he bid Moses to caution Aaron also, that he might not die as his sons died; these were Nadab and Abihu: when they offered before the Lord, and died ; offered strange fire, and died by flaming fire, as the Targum of Jonathan; or fire sent down from heaven, as Gersom, by lightning; (see Leviticus 10:1,2).
Matthew Henry Commentary
Verses 1-14 - Without entering into particulars of the sacrifices on the great day of atonement, we may notice that it was to be a statute for ever, til that dispensation be at an end. As long as we are continually sinning we continually need the atonement. The law of afflicting our souls for sin, is a statue which will continue in force till we arrive where all tears, even those of repentance, will be wiped from our eyes. The apostle observes it as a proof that the sacrifices could not take awa sin, and cleanse the conscience from it, that in them there was remembrance made of sin every year, upon the day of atonement, He 10:1, 3. The repeating the sacrifices, showed there was in them but feeble effort toward making atonement; this could be done only by offering up the body of Christ once for all; and that sacrifice neede not to be repeated. (Le 16:15-34)
