1Behold, how good and how pleasant it is For brethren to dwell together in unity! 2It is like the precious oil upon the head, That ran down upon the beard, Even Aaron's beard; That came down upon the skirt of his garments; 3Like the dew of Hermon, That cometh down upon the mountains of Zion: For there Jehovah commanded the blessing, Even life for evermore. Psalm 134 A Song of Ascents.
