Mt 18:21-35
Then came Peter unto Jesus and said: Lord, how often shall my brother offend against me, and I forgive him? Till seven times? Jesus saith to him: I say not to thee, till seven times; but till seventy times seven times. Therefore is the kingdom of heaven likened to a king, who would take an account of his servants. And when he had begun to take the account, one was brought to him, that owed him ten thousand talents. And as he had not wherewith to pay it, his lord commanded that he should be sold, and his wife and children and all that he had, and payment to be made.
