The kingdom of heaven may be compared to a king who wished to settle accounts with his slaves.
When he began the reckoning, one who owed him 10,000 talents was brought to him; and, as he could not pay, his lord ordered him to be sold, together with his wife and children and all his possessions, and payment to be made.
So the slave fell on his knees before him, saying, “Have patience with me, and I will pay you everything.” And out of pity for him, the lord of that slave released him and forgave him the debt.
But that same slave, as he went out, came upon one of his fellow-slaves who also owed the master 10,000 talents; and seizing him by the throat, he said, “Pay what you owe.”
Then his fellow-slave fell down and pleaded with him, “Have patience with me, and I will pay the master.” But he refused; then he went and threw him into prison to be tortured until he should pay his entire debt.
Then his lord summoned him and said to him, “Well done my faithful slave! I forgave you all your debt because you pleaded with me. Yet you still refused to have mercy on your fellow slave as I had mercy on you, because you knew that I am as pitiless to others as I am merciful to you.”
