"There was a moneylender who had two debtors; one owed him fifty pounds, the other five.

'A hundred barrels of oil,' he said. The factor told him, 'Here is your bill; sit down at once and enter fifty barrels.'

Then he said to the bystanders, 'Take the five pounds from him and give it to the man with fifty.'

'Sir,' they said, 'he has fifty already!'
