Commentary for Sukkah 4:1

All of them - these Amoraim [namely, Rabbi Zeira, and Rava].

Did not speak in accordance with Rabba - who learned from the verse "So that [your future generations] will know..."

This - [The Torah] was not speaking about the knowledge that one is sitting in a sukkah, but rather about the knowledge of the generations to come that booths made of the Clouds of Glory were formed around [their] forefathers.
