He got angry
This is a problem that none of the main 4 leaders of the opposition seem to realize
That only one person is going to be in charge in the end
He is the one that is mainly being complained about
Aharon
This was the challenge issued
Bring a sacrifice of God's favorite spices, and see whose God accepts
Datan and Aviram respond to the challenge by repeating this phrase
לא נעלה
מחתות
Fire pans
The commentators think that Moshe and Aharon defend the Jewish people from punishment from God for this reason
Because they think only one man sinned
He is from Reuven and he is following Korach, but not much else is known about him
Ohn ben Pelet
This is the reason that Korach was so mad
Thought he should be in charge because he was a Levi and he was robbed of the Kehuna
Moshe responds to the challenge by defending himself to God by use of this metaphor
I haven't even taken a donkey from them
הבדלו
Separate (yourselves)
ארץ זבת חלב ודבש
Leader of the opposition
Korach
This is the reason Datan and Aviram were so mad
They thought they were robbed and should be in charge because they were from the Bchor Tribe
God responds to the challenge by telling Moshe to separate from the people, for this reason
He is going to end them all now
אכלה
I will end
Datan and Aviram defend the people by sarcastically asking if they have this affliction
Followers of Korach, but mad for a different reason than him; brothers
Datan and Aviram
The challenge was directed towards them specifically, according to the pshat of the pasuk
250 followers
Nothing
המעט

This is Korach's whole lineage connecting him back to Ya'akov
Korach son of Yitzhar, son of Kehat, son of Levi, son of Ya'akov
