1 A Song of Ascents.2 Behold, how good and pleasant it is when brothers dwell in unity!3 It is like the precious oil upon the head, running down upon the beard, upon the beard of Aaron, running down on the collar of his robes! [ (Psalms 133:4) It is like the dew of Hermon, which falls on the mountains of Zion! For there the LORD has commanded the blessing, life for evermore. ]
