Psalm 133:1-3

BEHOLD, HOW good and how pleasant it is for brethren to dwell together in unity! It is like the precious ointment poured on the head, that ran down on the beard, even the beard of Aaron [the first high priest], that came down upon the collar and skirts of his garments [consecrating the whole body]. [Exod. 30:25, 30.] It is like the dew of [lofty] Mount Hermon and the dew that comes on the hills of Zion; for there the Lord has commanded the blessing, even life forevermore [upon the high and the lowly].
