Tafsiran Bilangan 16:27: Rashi, Or HaChaim, Siftei Chakhamim & Rav Hirsch

וַיֵּעָל֗וּ מֵעַ֧ל מִשְׁכַּן־קֹ֛רֶח דָּתָ֥ן וַאֲבִירָ֖ם מִסָּבִ֑יב וְדָתָ֨ן וַאֲבִירָ֜ם יָצְא֣וּ נִצָּבִ֗ים פֶּ֚תַח אָֽהֳלֵיהֶ֔ם וּנְשֵׁיהֶ֥ם וּבְנֵיהֶ֖ם וְטַפָּֽם׃

Maka mereka pun menjauh dari sekeliling kediaman Korah, Datan, dan Abiram. Lalu Datan dan Abiram keluar dan berdiri tegak di pintu kemah mereka, bersama istri-istri mereka, anak-anak mereka, dan anak-anak kecil mereka.

Rashi

יצאו נצבים [AND DATHAN AND ABIRAM] CAME OUT, STATIONING THEMSELVES [AT THE ENTRANCE OF THEIR TENT] — The word נצבים suggests that they stood with erect stature in a challenging attitude, ready to revile and to curse. The phrase is similar in meaning to (I Samuel 17:16) “And he stationed himself (ויתיצב) there for forty days”, which occurs in the story of Goliath (Midrash Tanchuma, Korach 3).

Or HaChaim

ויעלו מעל קרח ודתן ואבירם, They lifted themselves up from the residence of Korach, etc. The effrontery of Datan and Aviram in continuing to maintain a defiant posture though they had already been abandoned by their fellow travelers who had withdrawn in fear of being punished together with them, made a suitable impression on Moses so that he announced that the people would witness Divine intervention by the manner in which these people were going to die. This was to prove that he had not appointed himself as their leader but that G'd had appointed him at the time. The words את כל המעשים האלה mean that everything Moses had done including insignificant appearing things were all carried out at G'd's instruction. He now said that not only would these people die immediately but they would die a particularly gruesome death.

Siftei Chakhamim

With haughty bearing. Rashi is answering the question: What is meant by “went out and stood”? It is obvious that they did not go out while sitting! (Re’m). There is another question: What is meant by “went out and stood”? The word “went out” implies that they were moving, while the word “stood” implies that they were still. Rashi answers this question by explaining “to revile and blaspheme…”

Rashi

ונשיהם ובניהם וטפם AND THEIR WIVES, AND THEIR SONS, AND THEIR LITTLE ONES — Come and see how grievous a sin dissension is: for an earthly tribunal (more lit., a tribunal of here below) does not punish a person before he shows signs of puberty, the heavenly tribunal (more lit., the tribunal of above) not even before he is twenty years old, while here even the sucklings perished (Midrash Tanchuma, Korach 3).
