What significance does the cloud during the Transfiguration have?

In the account of the Transfiguration, the cloud that envelops Jesus and the disciples highlights the divine presence of God. This cloud represents a shift in biblical history; while clouds often symbolize God's unapproachable holiness, this moment introduces a bright cloud, signifying clarity and revelation through Jesus. It echoes God's presence during the giving of the law on Mount Sinai, but here, it represents the new covenant fulfilled in Christ. The voice from the cloud declares Jesus's authority, reinforcing that He is the fulfillment of the law and the prophecies, and emphasizes the new way God relates to humanity through His Son.
