Humanity attempting to climb too high without a proper foundation.
Climbing too high into divinity without truly earning it…
And they began to build, and in the fourth week they made brick with fire, and the bricks served them for stone, and the clay with which they cemented them together was asphalt which comes out of the sea, and out of the fountains of water in the land of Shinar. And they built it: forty and three years were they building it; its breadth was 203 bricks, and the height [of a brick] was the third of one; its height amounted to 5433 cubits and 2 palms, and [the extent of one wall was] thirteen stades [and of the other thirty stades].
— Jubilees 10:20–21, Charles' 1913 translation
Now it was Nimrod who excited them to such an affront and contempt of God. He was the grandson of Ham, the son of Noah, a bold man, and of great strength of hand. He persuaded them not to ascribe it to God as if it were through his means they were happy, but to believe that it was their own courage which procured that happiness. He also gradually changed the government into tyranny, seeing no other way of turning men from the fear of God, but to bring them into a constant dependence on his power... Now the multitude were very ready to follow the determination of Nimrod and to esteem it a piece of cowardice to submit to God; and they built a tower, neither sparing any pains, nor being in any degree negligent about the work: and, by reason of the multitude of hands employed in it, it grew very high, sooner than any one could expect; but the thickness of it was so great, and it was so strongly built, that thereby its great height seemed, upon the view, to be less than it really was. It was built of burnt brick, cemented together with mortar, made of bitumen, that it might not be liable to admit water. When God saw that they acted so madly, he did not resolve to destroy them utterly, since they were not grown wiser by the destruction of the former sinners [in the Flood]; but he caused a tumult among them, by producing in them diverse languages, and causing that, through the multitude of those languages, they should not be able to understand one another. The place wherein they built the tower is now called Babylon, because of the confusion of that language which they readily understood before; for the Hebrews mean by the word Babel, confusion. The Sibyl also makes mention of this tower, and of the confusion of the language, when she says thus:—"When all men were of one language, some of them built a high tower, as if they would thereby ascend up to heaven; but the gods sent storms of wind and overthrew the tower, and gave everyone a peculiar language; and for this reason it was that the city was called Babylon." - The Jewish-Roman historian Flavius Josephus, in his Antiquities of the Jews (c. 94 CE)
