THE ESSENES who wrote the second section of the Book of 1 Enoch, chapters 37–71 (called The Book of Parables), foresaw a coming Savior called the Son of Man. 

This was a new doctrine for Jews in the 1st century AD. The Zadokite priesthood in Jerusalem believed that faithful adherence to the Law would redeem the world. The Essenes of the Upper Galilee taught that the world had been so corrupted by the rebellious Watchers that only God’s direct intervention could make things right. 

1 Enoch is the first Jewish writing to put forward this doctrine, and the first to called the agent of God’s divine judgment the Anointed One, the Chosen One, and The Son of Man. And it’s clear in the text that the Son of Man is God Himself: 

For this purpose he became the Chosen One; he was concealed in the presence of (the Lord of the Spirits) prior to the creation of the world, and for eternity. (1 Enoch 48:6, Charlesworth translation 

Here are the Bible verses about angels Derek referred to: 

“See that you do not despise one of these little ones. For I tell you that in heaven their angels always see the face of my Father who is in heaven…” (Matt. 18:10, ESV) 

Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares. (Heb. 13:2, ESV)
