11:1-4 How soon men forget the most tremendous judgments, and go back to their former crimes! Though the desolations of the deluge were before their eyes, though they sprang from the stock of righteous Noah, yet even during his life-time, wickedness increases exceedingly. Nothing but the sanctifying grace of the Holy Spirit can remove the sinful lusts of the human will, and the depravity of the human heart. God's purpose was, that mankind should form many nations, and people all lands. In contempt of the Divine will, and against the counsel of Noah, the bulk of mankind united to build a city and a tower to prevent their separating. Idolatry was begun, and Babel became one of its chief seats. They made one another more daring and resolute. Let us learn to provoke one another to love and to good works, as sinners stir up and encourage one another to wicked works.
4. a tower whose top may reach unto heaven—a common figurative expression for great height (De 1:28; 9:1-6).
lest we be scattered—To build a city and a town was no crime; but to do this to defeat the counsels of heaven by attempting to prevent emigration was foolish, wicked, and justly offensive to God.
