In Daniel 7:9-14, the vision starts with Daniel seeing thrones being set up, and the "Ancient of Days" taking his seat. The term "Ancient of Days" refers to God in a majestic and eternal sense. The imagery here depicts God's majesty and authority, with his clothing as white as snow and his throne surrounded by flames.
A scene of judgment unfolds, with a multitude of heavenly beings serving before God. Books are opened, suggesting a divine judgment and assessment of actions. Then, the focus shifts to the judgment against a powerful and boastful horn (symbolizing a ruler or power) that is speaking great words. This horn is defeated and destroyed.
The vision then transitions to the portrayal of "one like a son of man" coming with the clouds of heaven. This figure, Jesus Christ, approaches the Ancient of Days and is granted dominion, glory, and an everlasting kingdom. This reflects divine authority being bestowed upon the "son of man," a righteous ruler who will reign with an eternal kingdom that will never be destroyed.
Overall, Daniel 7:9-14 is a symbolic depiction of God's ultimate authority, the judgment of earthly powers, and the establishment of a righteous and eternal kingdom under the rule of Jesus Christ.
