What are Watchers?

The Bible uses the word “watchers” in only a few special places but what are they or who are they? Watchers are those who are awake like a watchman in a watchtower. There is usually a watchman in the watchtower and so he could be called a watcher. To be a watchman necessarily means to be in a state of wakefulness and to also be watching. The word “Watcher” appears in both the plural and the singular forms in the Book of Daniel and seems to include the fact that they are in a state of holiness. The only exception to this that I could find was in Jeremiah 4:16 which says “Make mention to the nations, Yes, proclaim against Jerusalem, That watchers come from a far country and raise their voice against the cities of Judah” so even from this, to be a watcher is to be in a state of holiness and so we can now look at the Book of Daniel to see who or what these watchers are.
