'Bush' in the Bible

the angel of the LORD appeared to him in flaming fire from the center of a bush. As Moses continued to watch, amazingly the bush kept on burning, but was not consumed.

Then Moses told himself, "I'll go over and see this remarkable sight. Why isn't the bush burning up?"

When the LORD saw that he had gone over to look, God called to him from the center of the bush, "Moses! Moses!" He said, "Here I am."
