This is the one that got me focused on thinking about psalms aesthetically. The poetry of this psalm seems so modern in its stream-of-consciousness approach.

Look!

Look!

How good
  And how sweet
Brothers
  Living in unity.

Like rich goodness poured
  On the head
Oil flowing onto the beard
  Onto the beard of Aaron,
    Flowing onto his sacred robes;

Like the dew of Mt. Hermon
  Flowing onto Mt. Zion
For there Yahweh
  Has pronounced his blessing:
    Life forevermore.
