Numbers 16:40

40 a reminder to the Israelites that no outsider, who is not of the descendants of Aaron, shall approach to offer incense before the Lord, so as not to become like Korah and his company—just as the Lord had said to him through Moses.

Numbers 16:40 Meaning and Commentary

Numbers 16:40

[To be] a memorial unto the children of Israel
The whole body of them; this explains what is meant by sign, ( Numbers 16:38 ) ; that it was to put or keep in mind what follows:

that no stranger which [is] not of the seed of Aaron come near to offer
incense before the Lord;
not only any Gentile but any Israelite, and not any Israelite only, but any Levite; none but those of the family of Aaron might offer incense before the Lord;

that he be not as Korah and as his company;
this makes it clear that Korah perished at this time, though it is nowhere expressed; and it seems pretty plain from hence that he perished by fire, as his company, the two hundred fifty men with censers, did:

as the Lord said unto him by the hand of Moses;
either to Korah, who is the immediate antecedent, and who perished as the Lord had told him by Moses he should; so some understand it, mentioned by Aben Ezra and Jarchi; or else to Aaron, as they interpret it; and then the sense is, that none but those of Aaron's seed should offer incense, as the Lord had declared to him by Moses; see ( Numbers 3:10 ) ; or it may be rather to Eleazar, as Abendana, who did as the Lord spake to him by Moses, took up the censers of the men that were burnt, and got them beaten into broad plates, and covered the altar of burnt offering with them.

Numbers 16:40 In-Context

38 For the censers of these sinners have become holy at the cost of their lives. Make them into hammered plates as a covering for the altar, for they presented them before the Lord and they became holy. Thus they shall be a sign to the Israelites.
39 So Eleazar the priest took the bronze censers that had been presented by those who were burned; and they were hammered out as a covering for the altar—
40 a reminder to the Israelites that no outsider, who is not of the descendants of Aaron, shall approach to offer incense before the Lord, so as not to become like Korah and his company—just as the Lord had said to him through Moses.
41 On the next day, however, the whole congregation of the Israelites rebelled against Moses and against Aaron, saying, "You have killed the people of the Lord."
42 And when the congregation had assembled against them, Moses and Aaron turned toward the tent of meeting; the cloud had covered it and the glory of the Lord appeared.
