Psalms 133

133:1 A Song of degrees of David. Behold, how good and how
 pleasant [it is] for brethren to dwell together in unity!
133:2 [It is] like the precious ointment upon the head, that ran
 down upon the beard, [even] Aaron's beard: that went down to
 the skirts of his garment;
133:3 As the dew of Hermon, [and as the dew] that descended upon
 the mountains of Zion: for there the LORD commanded the
 blessing, [even] life for ever.
