“Esaias says: “The wolf also shall feed with the lamb, and the leopard shall take his rest with the kid; the calf also, and the bull, and the lion shall eat together; and a little boy shall lead them. …” I am quite aware that some persons endeavour to refer these words to the case of savage men, both of different nations and various habits, who come to believe, and when they have believed, act in harmony with the righteous. But although this is [true] now with regard to some men coming from various nations to the harmony of the faith, nevertheless in the resurrection of the just [the words shall also apply] to those animals mentioned. For God is rich in all things. And it is right that when the creation is restored, all the animals should … revert to the food originally given by God … that is, the productions of the earth.”

(This contains an allusion to the book of Isaiah Chapter 11, verse 6

Context: I believe that even amid today's mortar bursts and whining bullets, there is still hope for a brighter tomorrow. I believe that wounded justice, lying prostrate on the blood-flowing streets of our nations, can be lifted from this dust of shame to reign supreme among the children of men. I have the audacity to believe that peoples everywhere can have three meals a day for their bodies, education and culture for their minds, and dignity, equality and freedom for their spirits. I believe that what self-centered men have torn down men other-centered can build up. I still believe that one day mankind will bow before the altars of God and be crowned triumphant over war and bloodshed, and nonviolent redemptive good will proclaim the rule of the land. "And the lion and the lamb shall lie down together and every man shall sit under his own vine and fig tree and none shall be afraid." I still believe that We Shall overcome!'

And if David asks why I decline, I explain that it is because I have no desire to meet the woman.
"Come this time, father," he urged lately, "for it is her birthday, and she is twenty-six," which is so great an age to David, that I think he fears she cannot last much longer.

"To a Dog Injured in the Street"
The Desert Music and Other Poems (1954)
Context: The cries of a dying dog
are to be blotted out
as best I can.
René Char
you are a poet who believes
in the power of beauty
to right all wrongs.
I believe it also.
With invention and courage
we shall surpass
the pitiful dumb beasts,
let all men believe it,
as you have taught me also
to believe it.

The Law of the Jungle, Stanzas 1 and 2.
The Second Jungle Book (1895)
Context: p>Now this is the Law of the Jungle—as old and as true as the sky;
And the Wolf that shall keep it may prosper, but the Wolf that shall break it must die.As the creeper that girdles the tree trunk, the Law runneth forward and back;
For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.</p
