Genesis 7:20

Genesis 7:20, in plain English

The waters rise about 22 feet (fifteen cubits) above the mountaintops—a staggering depth that illustrates the total annihilation of the pre-flood world.

Why it's here

Giving an exact measurement matters. It tells you this is history, not legend. Someone is recording precisely what happened. The fifteen cubits also show that there's no escape—you can't climb higher than this. There's nowhere to go.

Who's speaking

The narrator provides a specific measurement of the water's depth

Where it sits in the story

The precision of measurement connects this to other specific details throughout Genesis—God is a God of order, of exactness, even in judgment. The flood isn't haphazard; it's measured, purposeful, and complete.

The scholarly reading

The waters rose above the mountaintops to a depth of fifteen cubits (approximately twenty-two to twenty-seven feet), ensuring no peak remained visible or accessible.

Language and setting

The specification of fifteen cubits (אַמָּה, ammah—approximately 45-51 centimeters per cubit in most scholarly estimates) provides quantitative precision rare in Genesis narrative, suggesting either eyewitness detail or theological emphasis on measured judgment. Fifteen cubits exceeds the highest arks could extend; the surplus emphasizes that height alone provides no refuge. The cubit measurement appears again in 8:5 (mountains becoming visible when waters decreased fifteen cubits), creating numerical coherence and suggesting deliberate theological calculation. Some scholars note that fifteen equals two plus two plus two plus... a symbolic completion, though this ventures into numerology beyond textual warrant.

Voice

The narrator provides precise measurement of the waters' depth above mountains.

Significance

The quantified depth establishes that judgment reaches beyond human measurement or escape—a finality that makes the ark's preservation by divine action alone (not human effort) theologically emphatic, foreshadowing the Christian assertion that salvation exceeds human calculation.

18So the waters continued to surge and rise greatly on the earth, and the ark floated on the surface of the waters.

19Finally, the waters completely prevailed upon the earth, so that all the high mountains under all the heavens were covered.

20The waters rose and covered the mountaintops to a depth of fifteen cubits.

21And every living thing that moved upon the earth perished—birds, livestock, animals, every creature that swarms upon the earth, and all mankind.

22Of all that was on dry land, everything that had the breath of life in its nostrils died.
