'Sun's' in the Bible

The light of the full moon will be like the sun's glare and the sun's glare will be seven times brighter, like the light of seven days, when the Lord binds up his people's fractured bones and heals their severe wound.

They will not be hungry or thirsty; the sun's oppressive heat will not beat down on them, for one who has compassion on them will guide them; he will lead them to springs of water.

because the sun's light failed. The temple curtain was torn in two.
