Psalm 133:1-3 NASB

[1] Behold, how good and how pleasant it is For brothers to live together in unity! [2] It is like the precious oil on the head, Running down upon the beard, As on Aaron’s beard, The oil which ran down upon the edge of his robes. [3] It is like the dew of Hermon Coming down upon the mountains of Zion; For the Lord commanded the blessing there—life forever.
