...and then the wounded knight, Sir Urre, set him up weakly, and prayed Sir Launcelot heartily, saying: Courteous knight, I require thee for God's sake heal my wounds, for methinketh ever sithen ye came here my wounds grieve me not. Ah, my fair lord, said Sir Launcelot, Jesu would that I might help you; I shame me sore that I should be thus rebuked, for never was I able in worthiness to do so high a thing. Then Sir Launcelot kneeled down by the wounded knight... And then he held up his hands, and looked into the east, saying secretly unto himself: Thou blessed Father, Son, and Holy Ghost, I beseech thee of thy mercy, that my simple worship and honesty be saved, and thou blessed Trinity, thou mayest give power to heal this sick knight by thy great virtue and grace of thee, but, Good Lord, never of myself. And then Sir Launcelot prayed Sir Urre to let him see his head; and then devoutly kneeling he ransacked the three wounds, that they bled a little, and forthwith all the wounds fair healed, and seemed as they had been whole a seven year. And in likewise he searched his body another three wounds, and they healed in likewise; and then the last of all he searched the which was in his hand, and anon it healed fair.
Then the King Arthur and all the knights kneeled down and gave thankings and lovings unto God and to his Blessed Mother. And even Sir Launcelot wept as he had been a child that had been beaten. - Le Morte d'Arthur, Sir Thomas Malory
