'Sun' in the Bible

‘The sun will be turned into darknessAnd the moon into blood,Before the great and glorious day of the Lord shall come.

Now, behold, the hand of the Lord is upon you, and you will be blind and not see the sun for a time.” And immediately a mist and a darkness fell upon him, and he went about seeking those who would lead him by the hand.

at midday, O King, I saw on the way a light from heaven, brighter than the sun, shining all around me and those who were journeying with me.

Since neither sun nor stars appeared for many days, and no small storm was assailing us, from then on all hope of our being saved was gradually abandoned.
