Psalms.
133.
A Song of degrees. Of David. Behold, how good and how pleasant it is for brethren to dwell together in unity! 
Like the precious oil upon the head, that ran down upon the beard, upon Aaron's beard, that ran down to the hem of his garments; 
As the dew of Hermon that descendeth on the mountains of Zion; for there hath Jehovah commanded the blessing, life for evermore.
