'Brightness' in the Bible

Therefore is justice far from us, neither does righteousness overtake us: we look for light, but, behold, darkness; for brightness, but we walk in obscurity.

Nations shall come to your light, and kings to the brightness of your rising.

The sun shall be no more your light by day; neither for brightness shall the moon give light to you: but Yahweh will be to you an everlasting light, and your God your glory.

For Zion's sake will I not hold my peace, and for Jerusalem's sake I will not rest, until her righteousness go forth as brightness, and her salvation as a lamp that burns.
