Genesis 11:9

Therefore is 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.

Babel means confusion. Hence is derived Babbler. Here was afterward founded Babylon the great seat of idolatry and persecution. This tower was then either rebuilt, or enlarged, and converted into the temple of Belus, which, according to history, was both higher and larger than St. Paul's cathedral.
