From the book:
1."Welcome, my lords, to Isengard!" he said. "We are the doorwardens. Meriadoc, son of Sadoc is my name; and my companion, who, alas! is overcome with weariness' - here he gave the other a dig with his foot - "is Peregrin, son of Paladin, of the house of Took. Far in the North is our home. The Lord Saruman is within; but at the moment he is closeted with one Wormtongue, or doubtless he would be here to welcome such honourable guests."
"Doubtless he would!" laughed Gandalf. "And was it Saruman that ordered you to guard his damaged doors, and watch for the arrival of guests, when your attention could be spared from plate and bottle?"
"No, good sir, the matter escaped him," answered Merry gravely. "He has been much occupied. Our orders came from Treebeard, who has taken over the management of Isengard. He commanded me to welcome the Lord of Rohan with fitting words. I have done my best."
2. All that is gold does not glitter.
Not all those who wander are lost.
The old that is strong does not wither.
Deep roots are not reached by the frost.
From the ashes a fire shall be woken.
A light from the shadows shall spring.
Renewed shall be blade that was broken.
The crownless again shall be king.
3. "Think you that Wormtongue had poison only for Theoden's ears? 'Dotard! What is the house of Eorl but a thatched barn where brigands drink in the reek, and their brats roll on the floor among the dogs?' Have you not heard these words before? Saruman spoke them, the teacher of Wormtongue. Though I do not doubt that Wormtongue at home wrapped their meaning in terms more cunning. My lord, if your sister's love for you, and her will still bent to her duty, had not restrained her lips, you might have heard even things as these escape them. But who knows what she spoke to the darkness, alone, in the bitter watches of the night, when all her life seemed shrinking, and the walls of her bower closing in about her, a hutch to trammel some wild thing in?"
From the movie:
1. "Fell deeds awake! Now for wrath, now for ruin, and the red dawn! Forth, Eorlingas!"
2. "Forward, and fear no darkness! Rise! Arise, riders of Theoden! Shields shall be shaken! Spears shall be splintered! A sword day, a red day, as the sun rises! DEATH!"
3. "I dreamed I saw a great wave climbing over green lands and above the hills. I stood upon the break. It was utterly dark in the abyss before my feet. A light shone behind me, but I could not turn. I could only stand there, waiting."
