De var inte säkra på Voldemorts skäl, men de litade på Dumbledore.
Blindförtroende i Dumbledore är ganska mycket en förutsättning för medlemskap i Phoenix-ordningen. Vi vet att Dumbledore inte berättade för Orden några detaljer om profetian. Han berättade bara att medlemmarna beställde att lita på Harry och skydda honom till varje pris.
Over Hermione's shoulder Harry saw [Kingsley] raise his wand and point it at Lupin's chest.
"The last words Albus Dumbledore spoke to the pair of us?"
"'Harry is the best hope we have. Trust him,'" said Lupin calmly.
(Deathly Hallows, Chapter 5, Fallen Warrior).
För ordermedlemmar som Kingsley och Lupine Dumbledores ord var allt de behövde.
Beställningsmedlemmarna - som alla andra - likväl kunde läsa pressspekulationen som förekommit i dagbladet.
The nature of that prophecy is unknown, although speculation is rife that it concerns Harry Potter, the only person ever to have survived the Killing Curse, and who is also known to have been at the Ministry on the night in question. Some are going so far as to call Potter the 'Chosen One', believing that the prophecy names him as the only one who will be able to rid us of He Who Must Not Be Named.
(Half-Blood Prince, Chapter 3, Will and Won't).
Så, även om Dumbledore aldrig avslöjade profetian mot dem, kunde de bilda utbildade gissningar om hur viktigt Harry var i ordningen med saker.
"And now, Harry, on a closely related subject...I gather that you have been taking the Daily Prophet over the last two weeks?"
"Yes," said Harry, and his heart beat a little faster.
"Then you will have seen that there have been not so much leaks, as floods, coconcerning your adventure in the Hall of Prophecy?"
"Yes," said Harry again. "And now everyone knows that I'm the one-"
"No, they do not," interrupted Dumbledore. "There are only two people in the whole world who know the full contents of the prophecy made about you and Lord Voldemort, and they are both standing in this smelly, spidery broom shed. It is true, however, that many have guessed, correctly, that Voldemort sent his Death Eaters to steal a prophecy, and that the prophecy concerned you."
(Half-Blood Prince, Chapter 4, Horace Slughorn).
De andra Ordningsmedlemmarna kände inte till den fulla sanningen om Harry men de gissade de breda detaljerna från Daglig profet . Och de litade på Dumbledores instruktioner ändå så att de skyddade Harry även utan att höra hela profetian.
