“And it came to pass on the third day, when it was morning, that there were thunders and lightnings and a thick cloud upon the mount, and the voice of a horn exceeding loud; and all the people that were in the camp trembled.”
– Exodus 19:16, JPS 1917 Tanach
“G-d hath so made it, that men should fear before Him.”
– Ecclesiastes 3:14, JPS
At Mount Sinai, the people in the camp trembled at the awesome display of H’Shem’s Presence, amidst the thunder and lightning. The people’s sense of yiras H’Shem (fear, awe, and reverence towards the L-RD) was elicited by the spectacular display, when the Commandments were given to B’nei Yisrael through Moshe (Moses). This may serve as an example for us, when we gather ourselves together, in order to receive the Torah anew in our lives on the day of Shavuot. The thunder and lightening that humbled the people at Sinai, demonstrate the importance of yiras H’Shem for our own lives. “The fear of H’Shem is the beginning of wisdom” (Psalm 111:10).
When we seek to develop awe, reverence, and proper respect towards H’Shem, we are planting a foundation within us that will bring wisdom and understanding into our lives. “And knowledge of the holy is understanding” (Proverbs 9:10). G-d seeks to bring our heart into alignment with His ways, by compelling us to seek teshuvah (repentance), that we may truly start anew. The powerful reminder of thunder is a natural occurrence that should serve as a wake-up call. According to the Talmud, thunder was created for this very purpose (Berachos 59a). On Shavuot, we stand once again, ready to leave our personal Mitzraim (Egypt) behind us, as we renew our commitment to keep the Covenant made at Mt. Sinai with B’nei Yisrael (the Children of Israel).
