'Brighter' in the Bible

Moreover the light of the moon will be like the light of the sun, and the light of the sun will be seven times brighter, like the light of seven days, in the day that Yahweh binds up the fracture of his people, and heals the wound they were struck with.

at noon, O king, I saw on the way a light from the sky, brighter than the sun, shining around me and those who traveled with me.
