The Fellowship of the Ring
Gildor was silent for a moment. "I do not like this news," he said at last. "That Gandalf should be late, does not bode well. But it is said: Do not meddle in the affairs of Wizards, for they are subtle and quick to anger. The choice is yours: to go or wait."
"And it is also said," answered Frodo: "Go not to the Elves for counsel, for they will say both no and yes." (1.3.165-6)
The Big Folk and the Little Folk (as they called one another) were on friendly terms, minding their own affairs in their own ways, but both rightly regarding themselves as necessary parts of the Bree-folk. Nowhere else in the world was this peculiar (but excellent) arrangement to be found. (1.9.4)
"No one lives in this land. Men once dwelt here, ages ago; but none remains now. They became an evil people, as legends tell, for they fell under the shadow of Angmar. But all were destroyed in the war that brought the North Kingdom to its end. But that is now so long ago that the hills have forgotten them, though a shadow still lies on the land."
"Where did you learn such tales, if all the land is empty and forgetful?" asked Peregrin. "The birds and beasts do not tell tales of that sort."
"The heirs of Elendil do not forget all things past," said Strider; "and many more things than I can tell are remembered in Rivendell." (1.9.30-2)
