Adam Clarke’s Commentary

Verse 9.   Therefore is the name of it called Babel] lbb babel, from lb bal, to mingle, confound, destroy; hence Babel, from the mingling together and confounding of the projects and language of these descendants of Noah; and this confounding did not so much imply the producing new languages, as giving them a different method of pronouncing the same words, and leading them to affix different ideas to them.

Besides Mr. Hutchinson’s opinion, (see ACC for Ge 11.4,) there have been various conjectures concerning the purpose for which this tower was built.  Some suppose it was intended to prevent the effects of another flood, by affording an asylum to the builders and their families in case of another general deluge.  Others think that it was designed to be a grand city, the seat of government, in order to prevent a general dispersion.  This God would not permit, as he had purposed that men should be dispersed over the earth, and therefore caused the means which they were using to prevent it to become the grand instrument of its accomplishment. Humanly speaking, the earth could not have so speedily peopled, had it not been for this very circumstance which the counsel of man had devised to prevent it.  Some say that these builders were divided into seventy-two nations, with seventy-two different languages; but this is an idle, unfounded tale.
