God has identified Himself as the eternal God. The God of the ancestors of those Israelites who were now suffering in Egypt. He has confirmed that He has not forgotten them. He is stating that now is the time for the promise of deliverance to be fulfilled. Moses, who once may have thought he could deliver his people, has learned that he can do nothing without God. That he must walk in the path that God lays out for him and for the people of Israel. God now begins to tell Moses what will happen in general terms. The specifics will be seen as time unfolds.
