Daniel 7:9-10

9“As I kept watching, thrones were set in place, and the Ancient of Days took his seat. His clothing was white like snow, and the hair of his head like whitest wool. His throne was flaming fire; its wheels were blazing fire.

10A river of fire was flowing, coming out from his presence. Thousands upon thousands served him; ten thousand times ten thousand stood before him. The court was convened, and the books were opened.
