'Sun's' in the Bible

Moreover, the light of the moon will be like the light of the sun, and the sun's light will be seven times brighter, like the light of seven full days, when the LORD binds up the bruises of his people and heals the wounds inflicted by his blow.

I am going to make the sun’s shadow that goes down on Ahaz’s stairway go back by 10 steps.” So the sun’s shadow went back the 10 steps it had descended.

so that from the sun's rising to the west people may know that there is none besides me. "I am the LORD, and there is no other."

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.
