Verse 29. The secret things - Having mentioned the amazing judgments of God upon the whole land and people of Israel, and foreseeing the utter extirpation which would come upon them for their wickedness, he breaks out into this pathetic exclamation, either to bridle their curiosity, who would be apt to inquire into the time and manner of so great an event; or to quiet his own mind, and satisfy the scruples of others, who perceiving God to deal so severely with his own people, when in the meantime he suffered those nations which were guilty of grosser atheism and idolatry, might thence take occasion to deny his providence or question the equity of his proceedings. To this he answers, that the ways and judgments of God, tho' never unjust, are often times hidden from us, unsearchable by our shallow capacities, and matter for our admiration, not our enquiry. But the things which are revealed by God and his word, are the proper object of our enquiries, that thereby we may know our duty, and be kept from such terrible calamities as these now mentioned.
