Moses was looking after the flock of his father-in-law Jethro, the priest of Midian; he led it to the far side of the desert and came to Horeb, the mountain of God.
The angel of Yahweh appeared to him in a flame blazing from the middle of a bush. Moses looked; there was the bush blazing, but the bush was not being burnt up.
Moses said, 'I must go across and see this strange sight, and why the bush is not being burnt up.'
When Yahweh saw him going across to look, God called to him from the middle of the bush. 'Moses, Moses!' he said. 'Here I am,' he answered.
'Come no nearer,' he said. 'Take off your sandals, for the place where you are standing is holy ground.
I am the God of your ancestors,' he said, 'the God of Abraham, the God of Isaac and the God of Jacob.' At this Moses covered his face, for he was afraid to look at God.
Yahweh then said, 'I have indeed seen the misery of my people in Egypt. I have heard them crying for help on account of their taskmasters. Yes, I am well aware of their sufferings.
And I have come down to rescue them from the clutches of the Egyptians and bring them up out of that country, to a country rich and broad, to a country flowing with milk and honey, to the home of the Canaanites, the Hittites, the Amorites, the Perizzites, the Hivites and the Jebusites.
Moses then said to God, 'Look, if I go to the Israelites and say to them, "The God of your ancestors has sent me to you," and they say to me, "What is his name?" what am I to tell them?'
God said to Moses, 'I am he who is.' And he said, 'This is what you are to say to the Israelites, "I am has sent me to you." '
God further said to Moses, 'You are to tell the Israelites, "Yahweh, the God of your ancestors, the God of Abraham, the God of Isaac and the God of Jacob, has sent me to you." This is my name for all time, and thus I am to be invoked for all generations to come.
