The Gem. learns out that Moshe was with Kllal Yisroel in their Tzar from the fact that he did not use a pillow or a cushion to sit on when his hands became tired. Just as Yaakov used stones for a pillow when he was travelling.

Isn't it more than likely that Moshe used a stone to sit on because that was the only thing that they could find there?

Thank you for listening
