שמות ג, ב: הַסְּנֶה וַיַרְ א וְהִנֵה הַסְּנֶה בֹּעֵר בָּאֵש
The Sforno makes two points here:
a)
He interprets the symbolism of the bush as the angel is the righteous of the Jews caught up, as it were, in the midst of the burning bush, which represents Egypt. The bush, which is not consumed, though enveloped in flames is symbolic of Egypt ravaged by the ten plagues but were not destroyed.
b)
Prophecy through mediums of images and visions wrapped in enigmas and riddles is not the method HaShem would use in later communications with Moshe. At this stage of Moshe’s calling, he was not yet prepared for direct, clear communications. From the moment of Sinai, when revelation occurred on the highest level of human experience, Moshe alone remained on that exalted plane to which all others reached only momentarily. From the moment on he spoke to HaShem, face to face, through a clear and vivid lens, and not through clouded visions and riddles.
