God tells Moses that he will send him to Pharaoh to demand that the Israelites be freed from Egypt. Moses objects that he is unworthy for such a task. God reassures Moses that he will be with him and provides a sign that will confirm his mission. When Moses asks for God's name to tell the Israelites, God responds with "I AM WHO I AM", emphasizing his eternal and unchanging nature. God instructs Moses to say that "I AM", the God of their ancestors, has sent him.
