 King Guy and Raynald were brought to Saladin's tent, where Guy was offered a goblet of water because of his great thirst.Guy took a drink and then passed the goblet to Raynald.Raynald's having received the goblet from King Guy rather than Saladin meant that Saladin would not be forced to offer protection to the treacherous Raynald (it was custom that if you were personally offered a drink by the host, your life was safe).
