'Sun' in the Bible

The sun shall be turned into darkness and the moon into blood, to usher in the day of the Lord-- that great and illustrious day;

and on the journey, at noon, Sir, I saw a light from Heaven--brighter than the brightness of the sun--shining around me and around those who were travelling with me.

Then, when for several days neither sun nor stars were seen and the terrific gale still harassed us, the last ray of hope was now vanishing.
