William Burkitt on Matthew 21:40

Observe here, At the first mentioning of the parable, the Pharisees express a bitter indignation against such wicked servants, not considering what a dreadful sentence they passed upon themselves and their own nation. Little did they think, that thereby they condemned their temple to be burnt, their city to be destroyed, their country to be ruined; but in these words they vindicate God, they condemn themselves, and own the justice of God, in inflicting the severest punishments on them.
