133:1 Behold, how good and pleasant it is
when brothers dwell in unity! 
2 It 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!
3 It is like the dew of Hermon,
which falls on the mountains of Zion!
For there the Lord has commanded the blessing,
life forevermore. (ESV)
 133:1 Or dwell together
He will drink from the brook by the way;
therefore he will lift up his head.
