'Ancient of Days' in the Bible

"I looked till the seats were prepared, and till the Ancient of Days sat him down. His clothing was white as snow, and the hairs of his head like the pure wool. His throne was like the fiery flame, and his wheels as the burning fire.

I saw in a vision by night, and behold, there came one in the clouds of heaven like the Son of Man - which went unto the Ancient of Days, before whom they brought him.

till the time that the Ancient of Days came, that the judgment was given to the chiefest saints; and till the time that the saints had the kingdom in possession.
