Then he says, that this day is known to Jehovah, in order that the faithful night depend on his good pleasure, and not too anxiously enquire about an event hidden from them and the whole world. The day then is known, says Zechariah, only to God, though he speaks of things well known, and which the Jews had at length to know by experience. But his object must be regarded, for his purpose was to restrain the godly, that they might not unnecessarily torment themselves, for we are wont to be too curious to know things: when God’s design is to calm us, and to make us rely on his providence, then many thoughts come across our minds, and toss us here and there, and thus we torment ourselves with anxiety. As then it is disease is innate in human nature, the Prophet supplies a seasonable remedy, — that the faithful are to allow themselves to be ruled by God, and to follow the example of their father Abraham, “The Lord will provide:” when he was in extremity and no escape was open he committed himself to God’s providence. So also Zechariah says, that it would be entirely dependent on the will of God alone, now to cover the heavens with darkness, and then to restore the sun, and also to blend darkness with light; and nothing is better for men than to check themselves, and not to enquire more than what is right, nor take away anything from God’s power, for whenever men murmur against God’s judgments, it is the same thing as though they wished to penetrate into heaven, and concede nothing to him except what they themselves think right. Then, in order to check this presumption, the Prophet says, that this day is known to Jehovah, so that the faithful might patiently wait until the ripened end should come, for our curiosity drives us here and there, so that we always wish to be certain about the end, “How long is this to endure?” and thus we complain against God; but when we are not able to subordinate our minds to his will, then we break forth as it were into a furious temper.
We hence see how useful a doctrine this clause contains, where the Prophet sets God as the judge and the arbitrator of all events, so that he afflicts the Church as long as it pleases him, sets bounds to adversities, and regulates all things as it seemeth good to him; and he also covers the heavens with thick clouds, and takes away the sight of the sun. All this then is what the Prophet would have us to know is in God’s power, and directed by his counsel. It now follows-
