'Brightness' in the Bible

Who is among you, fearing Jehovah, Hearkening to the voice of His servant, That hath walked in dark places, And there is no brightness for him? Let him trust in the name of Jehovah, And lean upon his God.

Therefore hath judgment been far from us, And righteousness reacheth us not, We wait for light, and lo, darkness, For brightness -- in thick darkness we go,

And come have nations to thy light, And kings to the brightness of thy rising.

To thee no more is the sun for a light by day, And for brightness the moon giveth not light to thee, And Jehovah hath become to thee A light age-during, and thy God thy beauty.

For Zion's sake I am not silent, And for Jerusalem's sake I do not rest, Till her righteousness go out as brightness, And her salvation, as a torch that burneth.
