What does the Bible say about the watchman in Isaiah 21?

In Isaiah 21:11-12, the watchman represents a prophetic voice responding to an inquiry about the night. This inquiry, echoing through time, asks what is happening in the spiritual and temporal realms. The watchman’s response indicates both the reality of calamity (the night) and the assurance of dawn (Christ). The role of the watchman is significant as it reflects a call to alert the people about the urgent need for awareness regarding spiritual conditions—encouraging them to seek understanding, both about sin and salvation available in Christ.
