The lion and the calf shall lie down together but the calf won’t get much sleep.

The lion and the lamb may, possibly, sumtime lay down in this world together for a fu minnits, but when the lion kums tew git up, the lamb will be missing.

The lion lying down with the lamb is the idea that is either projected back in time, saying that there was a time, or maybe that there will be a time, when the horrors of life are no longer necessary for life itself to exist. And the horrors of life are, of course, that everything eats everything else, and that everything dies, and that everything is born, and that the whole place is a charnel house. It's a catastrophe from beginning to end.
This is the vision of it being other than that. There's a strong idea that human beings can interact with reality in such a way that the tragic and evil elements of it can be mitigated, so that we can move closer to a state of being where we have the benefits of existence without the catastrophe that seems to go along with it.

Shepherds too soft who let their duty sleep, Encourage wolves to tear the lambs and sleep.

In that day the wolf and the lamb will live together; the leopard will lie down with the baby goat. The calf and the yearling will be safe with the lion, and a little child will lead them all. — Isaiah 11:6

You can't expect the fatted calf to share the enthusiasm of the angels over the prodigal's return.

the lion sleeps in the sun.
its nose on its paws.
it can kill a man.

Did you think the lion was sleeping because he didn't roar?

There is sitting and there is sitting. (...) Each one waits for the other to move, but the lion is poised, his tail twitching, while the fawn is frozen by fear, bowels turned to belly. No matter which way he bounds, the lion will have him, and he knows it.

He slept like an animal, well and lightly, faced in the opposite direction from that of a man; for a man going to sleep is about to escape into it while animals are prepared to escape out of it.

It's only on warm summer nights that the lions are restless. What they're seeing when they gaze during the day is nothing, their eyes are open but they don't see us -you can tell that when the lens of the pupil suddenlys shutters at the close swoop0 of one of the popcorn-begging pigeons through the bars of the cage. ... It's only on certain nights that their muscles flex and they begin to pant,their flanks heave as if they had been running through the dark night while other creatures shrank from their path, their jaws hang tense and wet as saliva flows as if in response to a scent of prey, at last they heave up their too-big heads, heavy, heavy heads, and out it comes. Out over the suburbs. A dreadful straining of the bowels to deliver itself; a groan that hangs above the houses in a low-lying cloud of smog and anguish.

Of two men sharing with a calf the milk of that calf's mother one eyes the calf with the thought that his tender flesh would provide good meat for him and his friends to feast upon at his approaching birthday. The other thinks of the calf as his brother of the teat and is filled with affection for the young beast and his mother. I say to you, the latter is truly nourished by that calf's meat; while the first is poisoned thereby. Aye, many things are put in the belly that should be put in the heart.

I hate it when my leg falls asleep. I know that means it's going to be up all night.

Up the road, in his shack, the old man was sleeping again. He was still sleeping on his face and the boy was sitting by him watching him. The old man was dreaming about the lions.
