Answer

That is not a derashah but a derush. It has no meaning at all, of course. If you want, add the kolel and then you’ll get a nice derush out of it. But as I said, all these things are meaningless.

What do you mean that it’s not a derashah but a derush?

Rabbi:
A derush is an invention that is not committed to any truth. Empty pilpulim that hang on gematrias and the like. I once defined the difference this way: a derush is judged by its conclusion, not by the quality of the inference or the arguments. If in the end the conclusion seems appealing to us, we don’t care that the arguments are weak and shaky. By contrast, pilpul is judged by the quality of the inference, regardless of the premises and the conclusion. It is the art of weaving together sources and halakhic arguments that lead to conclusions that are sometimes absurd.
Derash, as opposed to those two, is committed both to the inference and to the conclusion, but the inferences are not those of plain-sense interpretation; rather, they are based on the tools of derash (the hermeneutic principles).
