What does the word Watcher mean?

Watchman means: a person who guards the city day and night on the wall and provides danger warnings to the people in the city. The word Watcher comes from the Bible. Watchkeeping originally meant waking up without taking a nap, so it was used to describe a watchman who was absorbed.

The Bible is a series of 66 books. There are long and short; There are ancient works and more modern works, including: history, poetry, philosophy, and even private letters and lectures. The Bible is a classic belief of Jews and Europeans. It tells the history of Jews in ancient times and records the prophecies of prophets. When a large number of Jewish classics are translated into Greek, the Greek tabiblia is used to refer to these classics; Latin comes from the singular word Biblia, which later became the proper name of the official classics of Judaism and Christianity, and translated into Chinese is the "Bible".
