The Torah seems to be very specific about the promise never to destroy the Earth again by a flood. The Torah is very specific on that, it seems to be that way for a reason, and the same with being vague in other places. However, in this case, it is not vague.
In class, the teacher, paraphrased, thus, Hashem promised never to destroy the Earth again. Someone asked, but that is not what it says, it says only by flood, and that leaves other options open such as fire . .. not just flood. The instructor responded, well that’s what everyone assumes, there will not be another destruction by Hashem.
I was curious about that, and checked around, and was unable to find anything on that particular question, only the assumption. I was wondering if you knew any references or commentaries dealing with this question?
