In this week's Torah portion we read about the sin of the Golden Calf and Moses breaking the Tablets. After Moses pleaded with G-d to forgive the Jewish people, G-d instructed him to fashion new tablets, but unlike the first tablets which were given at Mount Sinai in an awesome event, these would be given very quitely without fanfare.
Rashi points this difference out and says that from here we see the power of the trait of modesty. For the First Tablets, which were given in great fanfare and noise, were destroyed, while the Second Tablets, given in private, endured.
