Compassion...pity. The same verb is used in both places. Shouldest not thou also have had mercy on thy fellow servant, even as I had mercy on thee? (Revised Version). The man's guilt lies in his unmercifulness in the face of mercy received.
The fact is patent; it stands for itself; it needs no amplification or enforcement. The king says no more, and the delinquent is equally silent; he has no excuse to offer. Convicted by his own conscience, he knows it is useless to sue for pardon or to expect further leniency.
So in the day of judgment no excuse can be admitted; it is too late to plead or argue when the sentence is past.
