'Ancient' in the Bible

I beheld till thrones were placed, and one that was ancient of days did sit: his raiment was white as snow, and the hair of his head like pure wool; his throne was fiery flames, and the wheels thereof burning fire.

I saw in the night-visions, and, behold, there came with the clouds of heaven one like unto a son of man, and he came even to the ancient of days, and they brought him near before him.

until the ancient of days came, and judgment was given to the saints of the Most High, and the time came that the saints possessed the kingdom.
