What does the Bible say about the role of witnesses in Revelation?

In Revelation 11, the two witnesses symbolize the law and the prophets, with Moses and Elijah representing the Old Testament's testimony to God's truth. Their ministry is essential for establishing the truth of God's Word, as the Lord Himself indicated that a testimony requires at least two witnesses. This reinforces the importance of divine revelation through the scriptures, demonstrating how God preserves His people through the proclamation of His Word amidst resistance and persecution.
