I don’t have a Makor for this so if anyone can tell me whether I’m right or wrong I’d appreciate it, but here goes:
Last year it came up in a discussion in the CR about the relevance of Tz’lofchad not having been involved in any Cheit in the Midbar and dying for his own sin. I thought that it was just their argument but that L’ma’aseh they would have received their share anyway. This year, however, I thought that maybe their point is that if their father had been part of Adas Korach then his share would have been forfeit, meaning his daughters couldn’t get it. Then I thought that maybe that’s why the Passuk talks about Dasan and Aviram and Adas Koras earlier in the Parsha when going through those who got a Chelek Ba’aretz. The Passuk mentions them to show that those involved did not get a Chelek. (Also, see Bava Basra 118b)
