    and he will give you the desires of your heart.

    and its leaf does not wither.
  In all that he does, he prospers.

Psalm 42:1–2

To the choirmaster. A Maskil of the Sons of Korah.

42:1   As a deer pants for flowing streams,

    for the living God.
  When shall I come and appear before God?
