Nephilim (nef-ill-leem) is the Hebrew word for giants. They were the offspring of human women and the sons of God (angels). Before I became a CF member I had gotten into this theology very deeply, at the time it was the only theology I cared to study. I used the name because when I became a member here I thought is was going to be the only subject I would talk about. LOL, Yeah, riiiiiight
The last 3 letters, iyr, is actually an old Hebrew word with Chaldean origins. It means to watch or gaze upon with eyes wide open. The word was used to name a certain type of angel called a "Watcher". They were believed to be the type of sons of God who sinned in Genesis 6. It is used once in the Bible in Daniel but many times in the Book of Enoch.
I chose to combine the two words and use it as my handle because I thought it perfectly discribed what I was doing. I had my eyes open and I was looking, seaching, studying the nephilim and all there was to know about them. However, it can also mean that I am watching out for them. Trust me though, from what I have learned about these beings, they are not someone you will ever want to meet or deal with!
For instance, Goliath, the giant that David slew, was a nephilim, and some believe the disembodied spirits of these beings are what we call demons.
