What does the Bible say about the responsibility of a watchman?

In Ezekiel 33, God appoints watchmen to warn the people of impending judgment. If the watchman sees danger coming and fails to sound the alarm, he is held accountable for the sins of those who perish as a result. Conversely, if he warns the people and they choose to ignore it, their blood is on their own heads. This highlights the serious responsibility entrusted to those who preach the Gospel, emphasizing the need for faithful declaration of God's word to warn against sin and the coming judgment.
