'Light' in the Bible

Woe [to] those who plan wickedness and evil deeds upon their beds! In the light of the morning they did it, because they have power in their hands.

You should not rejoice over me, O my enemy! When I fall I will stand up; when I sit in darkness Yahweh [will be] a light for me.

I will bear the rage of Yahweh, for I have sinned against him, until he pleads my cause and executes my justice. He will bring me out to the light; I will see his righteousness.
