Parshat Yitro includes one of the most awe-inspiring moments in the Torah, the giving of the Ten Commandments at Mount Sinai. The experience is described with an overwhelming sense of grandeur: “And it came to pass on the third day in the morning, that there were thunder and lightning, and a thick cloud upon the mount, and the voice of the shofar exceedingly loud; so that all the people in the camp trembled” (Exodus 19:16). The moment of revelation wasn’t just intellectual or spiritual, it was visceral, shaking the people to their core.
This thunderous moment invites us to consider a lesser-known but powerful Jewish blessing: the bracha we say upon hearing thunder—Baruch atah Adonai Eloheinu melech ha’olam shekocho ugevurato malei olam. “Blessed are you, Adonai, our God, sovereign of the universe, whose strength and might fill the world.”
Even though the rain we get here in Portland isn’t often accompanied by thunder, it’s still normal to think of thunder as nothing more than a natural phenomenon, a rumbling caused by lightning superheating the air. But in Jewish tradition, it’s understood as a reminder of God’s power, an echo of the divine voice that once thundered at Sinai. The blessing reminds us that moments of awe—whether from nature or from Torah—can shake us out of complacency and reawaken our awareness of the divine.
Rashi, commenting on the scene at Sinai, notes that the people “saw the thunder” (Exodus 20:15), an odd turn of phrase since thunder is heard, not seen. Clearly the experience at Sinai was beyond the realm of normal sensory perception; it was a full-body immersion in God’s presence. When we hear thunder today, we have a choice: we can dismiss it as an ordinary weather event, or we can let it be a moment of revelation, a reminder of a power greater than ourselves.
These days, moments as overwhelming as Sinai are few and far between, but the blessing on thunder invites us to cultivate awe even in the everyday. The sound of thunder can remind us of what the Israelites might have heard (or “seen”) when they received the Torah. It’s a call to reawaken our sense of purpose, just as the Israelites did when they stood at the foot of the mountain, trembling yet ready to accept their covenant with God.
