Adam Clarke on Proverbs 28:12

When righteous men do rejoice - When true religion is no longer persecuted, and the word of God duly esteemed, there is great glory; for the word of the Lord has then free course, runs, and is glorified: but when the wicked rise - when they are elevated to places of trust, and put at the head of civil affairs, then the righteous man is obliged to hide himself; the word of the Lord becomes scarce, and there is no open vision. The first was the case in this country, in the days of Edward VI.; the second in the days of his successor, Mary I: Popery, cruelty, and knavery, under her, nearly destroyed the Church and the State in these islands.
