psalm 133

Behold, how good and how pleasant it is
For brothers to dwell together in unity!
It is like the precious oil upon the head,
Coming down upon the beard,
Even Aaron’s beard,
Coming down upon the edge of his robes.
It is like the dew of Hermon
Coming down upon the mountains of Zion;
For there the LORD commanded the blessing—life forever.

A song of the ascents, of David.
