'Old' in the Bible

And Darius the Mede took the kingdom, being then about sixty-two years old.

I went on looking till the seats of kings were placed, and one like a very old man took his seat: his clothing was white as snow, and the hair of his head was like clean wool; his seat was flames of fire and its wheels burning fire.

I saw in visions of the night, and there was coming with the clouds of heaven one like a man, and he came to the one who was very old, and they took him near before him.

Till he came, who was very old, and the decision was made and the authority was given to the saints of the Most High; and the time came when the saints took the kingdom.
