God Called and spoke to Moses Exodus 3:
Now Moses was pasturing the flock of Jethro… The angel of the LORD appeared to him in a blazing fire from the midst of a bush; …. When the LORD saw that he turned … God called to him … and said, “Moses, Moses!” …. And he said, “Here I am.” …. He said also, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.”
