“’You are a stranger here, El-ahrairah,’ said the Black Rabbit. ‘You are alive.’
“’My lord,’ replied El-ahrairah, ‘I have come to give you my life. My life for my people.’
“The Black Rabbit drew his claws along the floor.
“’Bargains, bargains, El-ahrairah,’ he said. ‘There is not a day or a night but a doe offers her life for her kittens, or some honest captain of Owsla his life for his Chief Rabbit’s. Sometimes it is taken, sometimes it is not. But there is no bargain, for here what is is what must be.’”
