'Leopard' in the Bible

And the wolf will be living with the lamb, and the leopard will take his rest with the young goat; and the lion will take grass for food like the ox; and the young lion will go with the young ones of the herd; and a little child will be their guide.

And so a lion from the woods will put them to death, a wolf of the waste land will make them waste, a leopard will keep watch on their towns, and everyone who goes out from them will be food for the beasts; because of the great number of their sins and the increase of their wrongdoing.

Is it possible for the skin of the Ethiopian to be changed, or the markings on the leopard? Then it might be possible for you to do good, who have been trained to do evil.

After this I saw another beast, like a leopard, which had on its back four wings like those of a bird; and the beast had four heads, and the power of a ruler was given to it.
