2 And the angel of the Lord appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed.
3 And Moses said, I will now turn aside, and see this great sight, why the bush is not burnt.
4 And when the Lord saw that he turned aside to see, God called unto him out of the midst of the bush, and said, Moses, Moses. And he said, Here am I.
In Hebrew, “malach Yehovah” or angel of the Lord, was not a run-of-the-mill angel in the burning bush, bringing a message from God, it was God Himself that was about to speak to Moses; of that there is no scriptural doubt.
What the average person would come to doubt is the fact that a plant could burn without being consumed.
Dictamnus is a genus of flowering plant in the family Rutaceae, an herbaceous perennial, native to warm, open woodland habitats in southern Europe, North Africa and much of Asia. In the summer months, the whole plant is covered with a kind of flammable substance, which is gluey to the touch, and has a very fragrant, lemony aroma; but if it takes fire, it goes off with a flash all over the plant. The name “burning bush” derives from the volatile oils produced by the plant which can catch fire readily in hot weather.
