R. Eliezer says: to apprise us of the exalted state of Israel. When they all stood at Mount Sinai to receive the Torah, there were no blind ones among them, viz. "And all the people saw." And whence is it derived that there were no mutes among them? From (Exodus 19:8) "And all the people answered together." And whence is it derived that there were no deaf ones among them? From (Ibid. 24:7) "All that the L–rd has spoken, we shall do and we shall hear." And whence is it derived that there were no large ones among them? From (Ibid. 17) "And they stood at the foot of the mountain." And whence is it derived that there were no fools among them? From (Devarim 4:35) "You have been shown to know, etc."
