One day Moses was tending the flock of his father-in-law, Jethro, the priest of Midian, and he went deep into the wilderness near Sinai, the mountain of God.
References for Exodus 3:1
Suddenly, the angel of the LORD appeared to him as a blazing fire in a bush. Moses was amazed because the bush was engulfed in flames, but it didn't burn up.
"Amazing!" Moses said to himself. "Why isn't that bush burning up? I must go over to see this."
When the LORD saw that he had caught Moses' attention, God called to him from the bush, "Moses! Moses!" "Here I am!" Moses replied.
"Do not come any closer," God told him. "Take off your sandals, for you are standing on holy ground."
Then he said, "I am the God of your ancestors -- the God of Abraham, the God of Isaac, and the God of Jacob." When Moses heard this, he hid his face in his hands because he was afraid to look at God.
Then the LORD told him, "You can be sure I have seen the misery of my people in Egypt. I have heard their cries for deliverance from their harsh slave drivers. Yes, I am aware of their suffering.
So I have come to rescue them from the Egyptians and lead them out of Egypt into their own good and spacious land. It is a land flowing with milk and honey -- the land where the Canaanites, Hittites, Amorites, Perizzites, Hivites, and Jebusites live.
The cries of the people of Israel have reached me, and I have seen how the Egyptians have oppressed them with heavy tasks.
Now go, for I am sending you to Pharaoh. You will lead my people, the Israelites, out of Egypt."
"But who am I to appear before Pharaoh?" Moses asked God. "How can you expect me to lead the Israelites out of Egypt?"
Then God told him, "I will be with you. And this will serve as proof that I have sent you: When you have brought the Israelites out of Egypt, you will return here to worship God at this very mountain."
But Moses protested, "If I go to the people of Israel and tell them, 'The God of your ancestors has sent me to you,' they won't believe me. They will ask, 'Which god are you talking about? What is his name?' Then what should I tell them?"
God replied, "I AM THE ONE WHO ALWAYS IS. Just tell them, 'I AM has sent me to you.'"

God also said, "Tell them, 'The LORD, the God of your ancestors -- the God of Abraham, the God of Isaac, and the God of Jacob -- has sent me to you.' This will be my name forever; it has always been my name, and it will be used throughout all generations."
