"And the angel of the Lord [a dispatched one of the Lord] appeared unto him in a flame of fire out of the midst of the bush. . . .and when the Lord [Jehovah] saw that he turned aside to see, God [Elohim] called unto him out of the bush and said, Moses, Moses.
And he, Moses, said Here am I. . . .he said, I am the God [Elohim] of thy Father, the God of Abraham, the God of Isaac and the God of Jacob. . . ."
Exodus 3:2-6
