איוב, פרק ל״ז, פסוק ד׳

The raw power of a thunderstorm—the brilliant flash of lightning, the rolling thunder, and the heavy rain—serves as a striking display of God's greatness in the natural world. These forces weave together to reveal the immense power of the Creator. The sequence of these events carries deep meaning. Typically, the sudden flash of light appears first, followed closely by the booming sound of thunder [רש״י, מלבי״ם, ביאור שטיינזלץ, תקות אנוש]. Alternatively, this thunderous roar echoes only after God makes a divine decree, commanding the rain to fall [רמב״ן]. On a more spiritual level, this sequence hints at a filtered experience of the divine. Just as Moses could only experience God from behind, the thunder represents a reduced version of the divine voice. If humans were exposed to His direct, unfiltered presence, they simply could not survive the experience [אלשיך].

The roar itself is widely understood as the sound of the thunder [רוב הפרשנים]. As this sound grows louder and more intense [מלבי״ם], it expresses either the raw physical power of the storm [תקות אנוש, ביאור שטיינזלץ] or the ultimate majesty and grandeur of God Himself [מצודת ציון].

A central theme in this natural display is the absence of delay. One approach explains that once the thunder echoes, God does not hold back the clouds; the rain is released immediately to the earth [רש״י, אבן עזרא, רמב״ן]. Another perspective focuses on the human experience of the storm. Although it seems that thunder is delayed and arrives only after the lightning, this is merely an illusion caused by the limits of human senses. In reality, there is no delay at all. If human senses were capable of perceiving it, they would realize that the light and the sound are released at the exact same moment [מצודת דוד, מלבי״ם, תקות אנוש]. Another interpretation understands this dynamic as a sudden uprooting or cutting off of life [רש״י]. If God's voice were unleashed at its full strength, humans would not survive even a single moment to finish hearing it [אלשיך].

Ultimately, the storm unfolds with incredible speed the moment the thunder crashes. Yet, even before this mighty sound shakes the earth, God first listens to the quiet voice of those who pray and plead before Him [רש״י].
