Exodus 3:2-3

"And the angel of Jehovah 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. And Moses said, I will turn aside now, and see this great sight, why the bush is not burnt."

"The angel of Jehovah ..." As the context proves, "The Angel of Jehovah is not a created angel but Jehovah himself in his act of self-revelation."[10] This is merely another name for God, of which there are many in the Bible. Although this verse does not indicate it, there is reason to believe that the Angel of Jehovah should be identified with our Lord Jesus Christ, the Second Person of the Godhead; he is also called the Angel of the Covenant.[11]

"Flame of fire out of the midst of a bush ..." It is necessary to point out that this was an actual, objective event. It was not some kind of "vision" on Moses part, nor his mistaken thought that some kind of bush in full bloom was actually on fire. Men who do not believe the Bible have many fanciful perversions of what is written here. No, it happened, exactly as related here. Rylaarsdam called it a "vision."[12] Ellison said, "It was the spontaneous ignition of some dry thorn bush."[13] Ellison also added that such an example of spontaneous combustion "was nothing unusual," for which wisdom (?) we are thankful; because it makes it absolutely unnecessary to contradict anything that such a writer says!

To this point, Moses had never seen any kind of supernatural event in his entire life of about eighty years. His conclusion, therefore, was that it was some unusual natural phenomenon that he had encountered. Therefore, he turned aside to investigate it. Wonder of wonders! Although the bush was on fire, it was not being consumed. Such a contradiction of all that could have been expected required further investigation, so Moses went nearer.
