Genesis 11:20

"And the whole earth (i.e., the population of the earth, vid., Gen 2:19) was one lip and one kind of words:" unius labii eorundemque verborum. The unity of language of the whole human race follows from the unity of its descent from one human pair (vid., Gen 2:22). But as the origin and formation of the races of mankind are beyond the limits of empirical research, so no philology will ever be able to prove or deduce the original unity of human speech from the languages which have been historically preserved, however far comparative grammar may proceed in establishing the genealogical relation of the languages of different nations.

The old distinction between the sons of God and the sons of men (professors and profane) survived the flood, and now appeared again, when men began to multiply: according to this distinction we have, in this chapter, I. The dispersion of the sons of men at Babel (Gen 11:1-9), where we have, 1. Their presumptuous provoking design, which was to build a city and a tower (Gen 11:1-4). 2. The righteous judgment of God upon them in disappointing their design, by confounding their language, and so scattering them (Gen 11:5-9). II. The pedigree of the sons of God down to Abraham (v. 10-26), with a general account of his family, and removal out of his native country (Gen 11:27, etc.).
