Modern day biblical scholars have through their blurry transliterations lost the true definition of Gabriel and define him as ONLY an angel. Ex: From the Yahoo dictionary.
- In the Bible, an angel who explained signs from God and announced the conception, birth, and mission of Jesus to Mary.
However, Strong's concordance  defines Gabriel as "Man of God"
The roots of the Hebrew term Gabriy'el are "Geber"  and "El" 
Geber is defined as: "man, strong man, warrior (emphasizing strength or ability to fight) " And of course El is defined as: "god, god-like one, mighty one "
Now, if we were to look at Genesis 6:4 we would find the word GHIB-BORE which is plural for Men.

So, using the root Hebraic references we see that Gabriel was an Adamite [Man] in the flesh who was the Son of God (El Annunaqi).
