'Sun' in the Bible

the sun shall be changed to darkness and the moon to blood, before the great and gloriously appearing day of the Lord come.

And now behold, the Lord's hand is upon thee, and thou shalt be blind, not seeing the sun for a season. And immediately there fell upon him a mist and darkness; and going about he sought persons who should lead him by the hand.

at mid-day, on the way, I saw, O king, a light above the brightness of the sun, shining from heaven round about me and those who were journeying with me.

And neither sun nor stars appearing for many days, and no small storm lying on us, in the end all hope of our being saved was taken away.
