Psalm 133, a pilgrim song of David with three verses, is one of the short psalms. It describes the blessing of brotherly unity: "Behold, how good and pleasant it is for brethren to live in unity!" Arvo Pärt set this verse to music in a brightly reflective choral piece and dedicated it to his long-standing music editor at Universal Edition, Józef Stanislaw Durek.
