"Farewell" he said to Gandalf "I go to find the sun" - Legolas
"You cannot pass," he said. The orcs stood still, and a dead silence fell. "I am a servant of the Secret Fire, wielder of the flame of Anor. You cannot pass. The dark fire will not avail you, flame of Udûn. Go back to the Shadow! You cannot pass."
-Gandalf
"The Dark Lord has Nine. But we have One, mightier than they: the White Rider. He has passed through the fire and the abyss, and they shall fear him. We will go where he leads." - Aragorn
"These we will take!" said Gandalf suddenly. He cast aside his cloak and a white light shone forth like a sword in that black place. Before his upraised hand the foul Messenger recoiled, and Gandalf coming seized and took from him the tokens; coat, cloak, and sword. "These we will take in memory of our friend," he cried. "But as for your terms, we reject them utterly. Get you gone, for your embassy is over and death is near to you. We did not come here to waste words in treating with Sauron, faithless and accursed; still less of his slaves. Begone!" - Gandalf
"That there's some good in the world, Mr. Frodo, and it's worth fighting for." - Sam (in the movie)
