The Old Testament Prophets were individuals chosen by God to deliver messages to the people of Israel. They played a crucial role in guiding the nation, warning them about turning away from God, and calling for repentance. Their messages often included predictions about future events and the coming of the Messiah. Some of the most well-known prophets include Isaiah, Jeremiah, and Ezekiel. These prophets wrote books that are part of the Hebrew Bible, which is also known as the Tanakh. Their teachings emphasize themes of justice, mercy, and faithfulness, and they continue to influence religious thought today.
