Shmoel: Interesting. That should be Lifnei Iver, no? You attempted to get someone to admit that he would be Mevatel a Mitzvah.
R.T.: That’s an interesting P’shat. I always thought it was just a Nes that even when nature called for a rainbow, HKBH made one not show up. Yours makes more sense though, and doesn’t decrease the necessary Yad Hashem (because HKBH chooses when it rains). I like your P’shat actually. A lot. Thank you.
