Philo Judaeus De Confusione Linguarum 182

[182] For this reason God says, "Come, let us go down and confuse;" for the wicked, deserving to meet with such punishment as this, that the merciful, and beneficent, and bounteous, powers of God should become known to them chiefly by its inflictions. Knowing therefore that these powers are beneficial to the race of man, he has appointed the punishments to be inflicted by other beings; for it was expedient that he himself should be looked upon as the cause of well-doing, but in such a way that the fountains of his everlasting graces should be kept unmingled with any evils, not merely with those that are really evils, but even with those which are accounted such.
