'Ancient of Days' in the Bible

“I kept lookingUntil thrones were set up,And the Ancient of Days (God) took His seat;His garment was white as snowAnd the hair of His head like pure wool.His throne was flames of fire;Its wheels were a burning fire.

“I kept looking in the night visions,And behold, on the clouds of heavenOne like a Son of Man was coming,And He came up to the Ancient of DaysAnd was presented before Him.

until the Ancient of Days came and judgment was passed in favor of the saints of the Most High [God], and the time arrived when the saints (believers) took possession of the kingdom.
