The Revelation on Mt. Sinai . . . the giving of the Ten Commandments . . . our Torah portion, Yitro, describes the scene with great fanfare. The text has given cinematographers plenty of good material: thunder and lightning, smoke rising up into the sky, the whole mountain shaking violently, and the loud blaring of a horn, sometimes specifically called a shofar. Miraculous? Inspiring? Awesome? Yes, our Sages teach, but it was also really, really noisy. When the medieval rabbis read about Sinai, they focus our attention on that seemingly unimportant detail of just how loud it all must have been. One medieval commentator, the French rabbi known as Rashbam, teaches that the description of God answering Moses "in thunder" is really a metaphor about the volume of God's voice—God had to shout to be heard over all of the other noise at Sinai! (see Rashbam on Exodus 19:19). And God was shouting for good reason. "The blast [of the shofar] was louder than any sound that had ever been heard before," Rashbam's contemporary, the Spanish sage Ibn Ezra writes on Exodus 19:16.
