1 A Song of degrees. Of David. Behold, how good and how pleasant it is for brethren to dwell together in unity! 2 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; 3 As the dew of Hermon that descendeth on the mountains of Zion; for there hath Jehovah commanded the blessing, life for evermore.
