They know not - The judges are not acquainted with the law of God, on which all their decisions should be founded.
Neither will they understand - They are ignorant and do not wish to be instructed. They will not learn; they cannot teach. Happy England! How different from Judea, even in the days of Jehoshaphat! All thy judges are learned, righteous, and impartial. Never did greater men in their profession dignify any land or country - (1822).
All the foundations of the earth - "All the civil institutions of the land totter." Justice is at the head of all the institutions in a well regulated state: when that gets poisoned or perverted, every evil, political and domestic, must prevail; even religion itself ceases to have any influence.
