Genesis 11, 1-9
1 And the whole earth was of one language and of one speech.
2 And it came to pass, as they journeyed east, that they found a plain in the land of Shinar; and they dwelt there.
3 And they said one to another: 'Come, let us make brick, and burn them thoroughly.' And they had brick for stone, and slime had they for mortar.
4 And they said: 'Come, let us build us a city, and a tower, with its top in heaven, and let us make us a name; lest we be scattered abroad upon the face of the whole earth.'
5 And the LORD came down to see the city and the tower, which the children of men builded.
6 And the LORD said: 'Behold, they are one people, and they have all one language; and this is what they begin to do; and now nothing will be withholden from them, which they purpose to do.
7 Come, let us go down, and there confound their language, that they may not understand one another's speech.'
8 So the LORD scattered them abroad from thence upon the face of all the earth; and they left off to build the city.
9 Therefore was the name of it called Babel; because the LORD did there confound the language of all the earth; and from thence did the LORD scatter them abroad upon the face of all the earth.
Now we know that balel is the Hebrew word for confound or mix up; we are given this etymology right in the last verse of the story. It is not much of a stretch to think that, just as the Greeks heard "bar, bar, bar," when barbarians spoke, or we hear "blah, blah, blah," the Hebrews heard "bal, bal, bal."
We also know that Babel is a Hebrew loan word from the Akkadian word "bab-ilu," meaning "gate of God."
And we know that the particle el (cognate to "ilu" in Akkadian) means God or god, first in Canaanite and then in Hebrew. (So all those Biblical names that include the particle el, like Elizabeth or Daniel, have a little bit of God in their meaning.)
Like the story of the flood in Noah's Ark (in Genesis chapters 6 to 8), I have the fanciful notion that the story of the abandonment of the Tower of Babel and the confounding of languages has some basis in communal memory.
Once upon a time, linguists hypothesize, Indo-European peoples spoke a common language, now called the Proto-Indo-European (PIE) language. During prehistoric human migration, each group spoke whatever it called PIE, but added to the language as its circumstances required and borrowed from whatever native languages it came into contact with.
The people thought they could reach Heaven if they built the tower just a little higher. The Tower of Babel by Pieter Bruegel the Elder, 1563. Held by the Kunsthistorisches Museum in Vienna.
