His students were walking behind him. As soon as the girl saw him, she covered her hair and stood before Rabbi Yochanan asking him for some charity. Based on the commentary of the Akeidas Yitzchok we can say the following. We observe in nature that the more sophisticated a creature, the more fragile is its physical composition. On the other hand, if something appears to be of very durable construction, its function and potential is simple and uncomplicated.
Stones are durable, their impact on, and contribution to life is minimal.
Humans are extremely fragile organisms, but their potential and actual impact on life on this earth is tremendous. Brute strength equals unattractive form or packaging. We observe simple insects such as ants, able to build for themselves elaborate homes, storage facilities, etc. Powerful animals such as lions, on the other hand, are unable to make provisions for themselves. Their bodies seem exposed to all kinds of danger.
