AND MOSES SENT TO CALL DATHAN AND ABIRAM. Now Dathan and Abiram were the instigators of this controversy as much as Korach was, as Scripture states, Now Korach took … and Dathan and Abiram … and they rose up in the face of Moses with certain of the children of Israel etc.,84Above, Verses 1-2. meaning that they were the ones who roused them together against Moses and Aaron. Then Moses spoke [once] to Korach and to all his company,80Verse 5. and furthermore said to him: thou and all thy company,85Verse 11. for it was to him [Korach] that he spoke first, since he was the leader amongst them. Now amongst those that were gathered together were also the followers of Dathan and Abiram; therefore Moses wanted to speak to them also now, and to warn them about themselves and all those who were gathered together [with them], who were their company, and to appease them with good words, even comforting words86Zechariah 1:13. to Israel, since his [earlier] words to Korach were a conciliation only to the Levites.
The meaning of the expression and Moses sent is that Dathan and Abiram had gone away from his presence whilst he was speaking to Korach [as stated in Verses 5-7], and afterwards it again says, And Moses said unto Korach [Verse 8], who was still standing before him there, or maybe since Korach was a Levite he stayed in the camp of the Levites near the tent of Moses.87Accordingly, the speech of Moses to Korach, which is recorded in Verses 8-11, took place near Moses’ and Korach’s tents, and not near the Tent of Meeting. All this happened on the first day [of the rebellion], just as Moses said, thou and they, and Aaron tomorrow,80Verse 16. — this being the “morning” he mentioned to them: In the ‘morning’ the Eternal will make it known who are His.88Above, Verse 5.
It is possible that Dathan and Abiram, as princes of the congregation,54Above, Verse 2. were more distinguished than On the son of Peleth,54Above, Verse [1]. and if they would have been won over to Moses, On would have followed their counsel; therefore Moses did not send for him. Thus On did not come, and was not present together with them [Dathan and Abiram], nor was he with Korach’s company; since he left him when Dathan and Abiram went away, while Moses was debating with Korach, and he never returned [to Korach’s company], because he changed his mind [after his original participation] on the advice of his wife who saved him, according to the words of our Rabbis.89Sanhedrin 109b. She said to her husband: “What benefit will you have from this controversy? Either Moses remains master and you are his disciple, or Korach becomes master and you are his disciple!” For Scripture does not mention him [On] as one who was swallowed up [in the earth] together with Dathan and Abiram, nor was he among the company of those that gathered together against the Eternal90See further, 27:3. who offered the incense, since there were two hundred and fifty men besides the four91I.e., Korach, Dathan, Abiram, and On the son of Peleth. Now since Scripture mentions these four men besides the two hundred and fifty (Verse 2), and the fire which burnt those who offered the incense, destroyed two hundred and fifty men (further, Verse 35), it follows that On must have been saved. The death of Korach, Dathan, and Abiram, however, is expressly mentioned separately (ibid., Verses 27, and 32-33). mentioned at first.

Rashi
And he made of them seventy thousand, etc. The reason he mentions them again and mentions the number is that he interrupted the topic; therefore, he had to repeat it again now. And he did not stop until he finished the entire [account of the] building, and he says immediately (3:1): “And Solomon commenced to build, etc.” Now, even with one verse, it is customary to interrupt the topic and [then] to begin [again] with the previous statement, e.g., (Num. 16:6): “Do this: take yourself, etc.” And the morrow, it says (ibid. 16f.): “And Moses said to Korah: You and all your band, etc.,” and he repeats and says, “and let each man take his censer and place, etc.” Since he interrupted with many verses, it was necessary to rewrite it, and how much more so here.

ואכלה אותם כרגע, “so that I may consume them in a moment;” if you were to ask that we have a rule that punishment must not be meted out unless preceded by a warning, Moses had warned them in the name of G-d when he had said to them to come up for judgment in the presence of the Lord on the following morning together with Aaron in verse 16. However, Korach had not complied. This is why G-d could be angry at them without delay, seeing that Korach. instead of complying with G-d’s instruction had assembled the whole congregation as per verse 19, in order to get the maximum publicity value out of his rebellion. As a result, G-d was justified in carrying out sentence immediately. The participants and guilty people had already all been warned. (17,10)
