The Idra Zuta, part of the Zohar, gets right into it. It poses the question: what exactly is a watcher? And then it answers it, drawing on the Book of Samuel.

The explanation links the term "watcher" (ir) to the Hebrew word for "enemy" (ar), as in, “and become your enemy (ar)” (I Samuel 28:16). Think about that for a second. Enemies? Watchers? What's the connection?

Well, the Idra Zuta explains that judgments rise against those who are not favored "above." Those who rise to execute these judgments? They are considered their enemies. Hence, the name "watchers." They're the enforcers, the ones carrying out the divine decrees, sometimes in a way that feels… well, adversarial.

But here's where it gets interesting. It’s not all doom and gloom. The Idra Zuta goes on to say that decrees are formed in two ways: with mercy and with judgment. So, these beings aren't just instruments of harsh justice. They're also associated with compassion.

This duality is reflected in their full title: "watchers and holy ones." Watcher indicates judgment, while "holy one" implies mercy. This echoes the verse from Daniel (4:14), "This matter is by the decree of the watchers, and the sentence by the word of the holy ones.”

So, the next time you encounter the term "watcher" in a mystical text, remember that they represent more than just divine punishment. They embody a complex interplay of justice and mercy, two forces that, according to the Idra Zuta, are essential to the unfolding of divine will. Perhaps, they are a reminder that even in judgment, there is a spark of holiness, a potential for redemption.
