The need to unite with the Moshe of the generation

There is a tzaddik like Moshe in the world, the secret of da'as, and when the rest of the people in his generation are connected and unified with him as one they are called a generation of knowledge. This is the secret of the revival of the dead.

The opposite is true when there is separation between them, they are separated from life energy and knowledge, and this is the reason for the exile of Egypt and Pharaoh, the secret of the "back of the neck" which is behind the da'as. Thus it can be understood that when they spoke evil of Moshe and separated from da'as this is the cause of exile.
