Verses 28, 29. - And Noah lived after the flood three hundred and fifty years. I.e. to the fifty-eighth year of the life of Abram, and was thus in all probability a witness of the building of the tower of Babel, and of the consequent dispersion of mankind. And all the days of Noah were nine hundred and fifty years: and he died. Tuch, Bleek, and Colenso connect these verses with ver. 17, as the proper continuation of the Elohist's work.
And Noah lived after the flood three hundred and fifty years. So that he not only saw the old world, and the wickedness of that, and the destruction of it for it, but an increase of wickedness again, the building of the tower of Babel, the confusion of languages, the dispersion of his offspring, and the wars among them in the times of Nimrod, and others: however, it was a blessing to mankind that he lived so long after the flood in the new world, to transmit to posterity, by tradition, the affairs of the old world; and to give a particular account of the destruction of it, and to instruct them in the doctrines and duties of religion. By this it appears, that he lived within thirty two years of the birth of Abraham. The Jews conclude from hence, that he lived to the fifty eighth year of Abraham's life: it may be remarked, that it is not added here as usual to the account of the years of the patriarchs, "and he begat sons and daughters"; from whence it may be concluded, that he had no more children than the three before mentioned, as well as from the silence of the Scriptures elsewhere, and from the old age of himself and his wife, and especially from what is said; see Gill on Genesis 9:19.
