On the back side of the desert Moses turns aside to a bush ablaze yet unconsumed, and hears the divine name.
Exodus 3:14–15World English Bible
14God said to Moses, “I AM WHO I AM,” and he said, “You shall tell the children of Israel this: ‘I AM has sent me to you.’”15God said moreover to Moses, “You shall tell the children of Israel this, ‘Yahweh, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’ This is my name forever, and this is my memorial to all generations.
