Psalm 133

1Behold, how good and pleasant it is
   when brothers dwell in unity!Or dwell together 2It is like the precious oil on the head,
   running down on the beard,
on the beard of Aaron,
   running down on the collar of his robes! 3It is like the dew of Hermon,
   which falls on the mountains of Zion!
For there the LORD has commanded the blessing,
   life forevermore.
