This do, take you censers,.... Vessels to put incense in to offer, which was the business of the priests:
Korah, and all his company; the two hundred fifty princes that were with him, for so many we read took censers, and offered incense, Numbers 16:18.
Take your censers, Korah, and all his company, &c.--that is, since you aspire to the priesthood, then go, perform the highest function of the office--that of offering incense; and if you are accepted well. How magnanimous the conduct of Moses, who was now as willing that God's people should be priests, as formerly that they should be prophets (Numbers 11:29). But he warned them that they were making a perilous experiment.
To leave the decision of this to the Lord, Korah and his company, who laid claim to this prerogative, were to take censers, and bring lighted incense before Jehovah. He whom the Lord should choose was to be the sanctified one. This was to satisfy them. With the expression רב־לכם in Numbers 16:7, Moses gives the rebels back their own words in Numbers 16:3. The divine decision was connected with the offering of incense, because this was the holiest function of the priestly service, which brought the priest into the immediate presence of God, and in connection with which Jehovah had already shown to the whole congregation how He sanctified Himself, by a penal judgment on those who took this office upon themselves without a divine call (Leviticus 10:1-3). Numbers 16:8. He then set before them the wickedness of their enterprise, to lead them to search themselves, and avert the judgment which threatened them. In doing this, he made a distinction between Korah the Levite, and Dathan and Abiram the Reubenites, according to the difference in the motives which prompted their rebellion, and the claims which they asserted. He first of all (Numbers 16:8-11) reminded Korah the Levite of the way in which God had distinguished his tribe, by separating the Levites from the rest of the congregation, to attend to the service of the sanctuary (Numbers 3:5., Numbers 8:6.), and asked him, "Is this too little for you? The God of Israel (this epithet is used emphatically for Jehovah) has brought thee near to Himself, and all thy brethren the sons of Levi with thee, and ye strive after the priesthood also. Therefore...thou and thy company, who have leagued themselves against Jehovah:...and Aaron, what is he, that he murmur against him?" These last words, as an expression of wrath, are elliptical, or rather an aposiopesis, and are to be filled up in the following manner: "Therefore,...as Jehovah has distinguished you in this manner,...what do ye want? Ye rebel against Jehovah! why do ye murmur against Aaron? He has not seized upon the priesthood of his own accord, but Jehovah has called him to it, and he is only a feeble servant of God" (cf. Exodus 16:7). Moses then (Numbers 16:12-14) sent for Dathan and Abiram, who, as is tacitly assumed, had gone back to their tents during the warning given to Korah. But they replied, "We shall not come up." עלה, to go up, is used either with reference to the tabernacle, as being in a spiritual sense the culminating point of the entire camp, or with reference to appearance before Moses, the head and ruler of the nation. "Is it too little that thou hast brought us out of a land flowing with milk and honey (they apply this expression in bitter irony to Egypt), to kill us in the wilderness (deliver us up to death), that thou wilt be always playing the lord over us?" The idea of continuance, which is implied in the inf. abs., השׂתּרר, from שׂרר, to exalt one's self as ruler (Ges. 131, 36), is here still further intensified by גּם. "Moreover, thou hast not brought us into a land flowing with milk and honey, or given us fields and vineyards for an inheritance (i.e., thou hast not kept thy promise, Exodus 4:30 compared with Numbers 3:7.). Wilt thou put out the eyes of these people?" i.e., wilt thou blind them as to thy doings and designs?
