What does the Bible say about watchmen?

In Scripture, watchmen are often depicted as those who are assigned to guard and protect, specifically regarding the spiritual well-being of others. For instance, Ezekiel 3:16-18 talks about how God appointed Ezekiel as a watchman over Israel, instructing him to warn the people of their wicked ways. Similarly, Isaiah 52:8 depicts watchmen as those who lift their voices together in worship and proclamation. God's faithful preachers serve as watchmen, guarding against spiritual dangers and declaring the truth of the gospel to bring salvation to the elect.
