John Calvin on Genesis 11:9

9. Therefore is the name of it called Babel . Behold what they gained by their foolish ambition to acquire a name! They hoped that an everlasting memorial of their origin would be engraven on the tower; God not only frustrates their vain expectation, but brands them with eternal disgrace, to render them execrable to all posterity, on account of the great mischief indicted on the human race, through their fault. They gain, indeed, a name, but not each as they would have chosen: thus does God opprobriously cast down the pride of those who usurp to themselves honors to which they have no title. Here also is refuted the error of those who deduce the origin of Babylon from Jupiter Belus. בבל, ( Babel ,) is derived from בלל, ( balel ,) which signifies to confound. See Schindler’s Lexicon, sub voce בלל. The name Babel signifies, as Bishop Patrick says, “confusion; so frivolous is their conceit, who make it to have been called by this name, from Babylon, the son of Belus.” — Ed
