11:5-9 Here is an expression after the manner of men; The Lord came down to see the city. God is just and fair in all he does against sin and sinners, and condemns none unheard. Pious Eber is not found among this ungodly crew; for he and his are called the children of God; their souls joined not themselves to the assembly of these children of men. God suffered them to go on some way, that the works of their hands, from which they promised themselves lasting honour, might turn to their lasting reproach. God has wise and holy ends, in allowing the enemies of his glory to carry on their wicked projects a great way, and to prosper long. Observe the wisdom and mercy of God, in the methods taken for defeating this undertaking. And the mercy of God in not making the penalty equal to the offence; for he deals not with us according to our sins. The wisdom of God, in fixing upon a sure way to stop these proceedings. If they could not understand one another, they could not help one another; this would take them off from their building. God has various means, and effectual ones, to baffle and defeat the projects of proud men that set themselves against him, and particularly he divides them among themselves. Notwithstanding their union and obstinacy God was above them; for who ever hardened his heart against him, and prospered? Their language was confounded. We all suffer by it to this day: in all the pains and trouble used to learn the languages we have occasion for, we suffer for the rebellion of our ancestors at Babel. Nay, and those unhappy disputes, which are strifes of words, and arise from misunderstanding one another's words, for aught we know, are owing to this confusion of tongues. They left off to build the city. The confusion of their tongues not only unfitted them for helping one another, but they saw the hand of the Lord gone out against them. It is wisdom to leave off that which we see God fights against. God is able to blast and bring to nought all the devices and designs of Babel-builders: there is no wisdom nor counsel against the Lord. The builders departed according to their families, and the tongue they spake, to the countries and places allotted to them. The children of men never did, nor ever will, come all together again, till the great day, when the Son of man shall sit upon the throne of his glory, and all nations shall be gathered before him.
