Psalms 133:2

¹ Behold, how good and how pleasant it is for brethren to dwell together in unity!

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 garments;

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 evermore.

Do read the surrounding verses too, because the context often says more than a single verse.
