1st Book of Enoch 9: 1- 11

In this chapter we see that nothing is hidden from God. The leader of the rebellion is mentioned in Chapter 6 isn't the same declared in Chapter 9. The Azazel is identified as that leader who taught mankind forbidden knowledge, with Semjaza and the associates. In my opnion Semjaza is a Nephalem that was created between Genesis 3 to 6 and presented the plan to rebel against God to the angels that envied Satan. Satan did drew with his tail 1/3 or 33% of the host of heaven into deception. This is a practice of over and over again done in the Bible as Satan uses human shields to do his will, but if you have eyes to see, and ears to hear you will understand the evil principality done in the darkness. God sees and knows all.
