'Light' in the Bible

Woe to those devising iniquity, And working evil on their beds, In the light of the morning they do it, For their hand is -- to God.

Thou dost not rejoice over me, O mine enemy, When I have fallen, I have risen, When I sit in darkness Jehovah is a light to me.

The indignation of Jehovah I do bear, For I have sinned against Him, Till that He doth plead my cause, And hath executed my judgment, He doth bring me forth to the light, I look on His righteousness.
