God's Voice Speaks in Borrowed Thunder

Scripture uses human language to describe God. It has to. Nothing else is available. But this creates a problem that the rabbis of the Mekhilta DeRabbi Yishmael took seriously: when the Torah says God's voice was like roaring waters, it is comparing the Creator to something He created. When it says the Sinai theophany was like the smoke of a kiln, it is measuring the infinite against a furnace. The comparison is backwards.

The Mekhilta -- a tannaitic midrash compiled by the school of Rabbi Ishmael in the second and third centuries in Roman Palestine -- addresses this not by avoiding the metaphors but by explaining why they are there and what they are doing. It establishes a principle across three consecutive examples, building to a foundation for how the entire tradition should read Scripture's physical language about God.

The Three Examples the Mekhilta Uses

The first example is the lime kiln at Sinai. When God descended onto the mountain, the smoke rose "like the smoke of a kiln" (Exodus 19:18). A kiln is a human technology, built by human hands to fire clay. Who gave the fire its strength? God did. Why, then, is the divine descent compared to human industry?

The second example is from Amos. (Amos 3:8) says "The lion has roared, who will not fear?" The lion's roar is an analogy for the divine word compelling the prophet to speak. But who created the lion's roar? Who gave the lion its power? The comparison uses God's own creation as a measure for God. The same backwards structure.

The third example, preserved in the Mekhilta's text on Tractate Bachodesh, is from (Ezekiel 43:2): "And the glory of the God of Israel came by way of the East, His voice like the voice of many waters." The prophet Ezekiel, writing in the sixth century BCE among the exiles in Babylon, describes God's return to the Temple. The divine voice is compared to the overwhelming roar of floods, to water crashing with the accumulated force of a great current. And again: who gave the waters their power? Who created the oceans and every river? Is it not God?

The Answer the Mekhilta Gives

The Mekhilta states its principle plainly: "We use the epithet of His creations to help the ear by what it is accustomed to hearing." The metaphors are not philosophical errors. They are concessions to the limitation of human perception. The ear has heard the kiln's roar. The ear has heard lions. The ear has heard the sea. These are the most powerful sounds within human experience. Scripture uses them to point at something beyond them, knowing they will fail, using them anyway because they are the best available approach.

This is one of the most important hermeneutical principles in the entire Mekhilta. It explains not just three verses but a method. Every time Scripture applies a physical attribute to God -- strength, fire, hand, voice, wrath -- the reader is being given a concession, not a definition. The metaphor is not describing what God is. It is giving the human ear something it can process, in the hope that the ear will hear past the image toward what cannot be imaged.

Why Ezekiel's Vision Needed This Language

The passage in Ezekiel (43:1-5) describes the return of the divine presence to the Temple after the Babylonian destruction. It is one of the most technically precise visions in the Hebrew Bible -- directions, measurements, a gate facing east, glory arriving from the east just as it had departed (Ezekiel 11:23). And in the middle of this precise architectural vision, the sound of God's return is described as "many waters."

The choice is not arbitrary. Ezekiel had described the divine chariot vision in (Ezekiel 1) using the same image: "a voice from above the expanse" compared to water, to a great roaring. The "many waters" returns here to mark continuity -- this is the same presence that Ezekiel saw by the Chebar River in Babylon, now returning to Zion. The overwhelming sound signals that nothing has diminished in the interim. The exile did not weaken what was exiled.

The Mekhilta reads this vision alongside the Sinai theophany because both involve the same communicative problem: how does a human account describe what no human ear can adequately receive? Sinai used the kiln. Ezekiel used the flood. Both images pull from the category of "most powerful sound we have." Both point beyond themselves to something their metaphors cannot contain.

The Mercy in the Metaphor

The Mekhilta's principle -- that Scripture uses the language of creation to help the human ear -- is also a statement about God's willingness to be misunderstood in the service of being heard. He could have spoken at Sinai in silence. He could have given the Torah without thunder and fire and the report that His voice shook the mountain. The phenomenology of the theophany was not necessary for the content.

It was there for Israel. The kiln-smoke, the trembling mountain, the voice like many waters -- these were the tradition's way of saying: something entered human experience at Sinai that could not be entered quietly. The borrowed thunder was a mercy. It gave the people sounds their ears knew so they could begin to approach what their ears could not know. The Mekhilta's teaching on these three verses is that the gap between the metaphor and what it describes is not a failure. It is the shape of every genuine encounter with the divine -- you reach for the largest sound you have and find it is still not enough, and you reach anyway.
