Famous quotes containing the word sun:

    Behold, O God our shield, and look upon the face of thine anointed.
    For a day in thy courts is better than a thousand. I had rather be a doorkeeper in the house of my God, than to dwell in the tents of wickedness.
    For the Lord God is a sun and shield: the Lord will give grace and glory:
    Bible: Hebrew Psalm LXXXIV (l. LXXXIV, 9–11)

    And if sun comes
    How shall we greet him?
    Shall we not dread him,
    Shall we not fear him
    After so lengthy a
    Session with shade?
    Gwendolyn Brooks (b. 1917)

    I declare
    Two lineages electrify the air,
    That will like pennons from a mast
    Fly over sleep and life and death
    Till sun is powerless to decoy
    A single seed above the earth:
    Lineage of sorrow: lineage of joy....
    Philip Larkin (1922–1986)
