God denounces the woes that shall forerun the destruction of the world, that so they may the less disturb when they come, as having been foreknown. For darts strike the less which are foreseen. And so He says, But when ye shall hear of wars and commotions, &c. Wars refer to the enemy, commotions to citizens. To shew us then that we shall be troubled from within and without, He asserts that the one we suffer from the enemy, the other from our own brethren.
