133:1 A song of degrees or Psalme of David. Behold, howe good and howe comely a thing it is, brethren to dwell euen together.
133:2 It is like to the precious oyntment vpon the head, that runneth downe vpon the beard, euen vnto Aarons beard, which went downe on the border of his garments:
133:3 And as the dew of Hermon, which falleth vpon the mountaines of Zion: for there the Lord appointed the blessing and life for euer.
The verse centers on "song", "degrees", "psalme", "david", "behold", "howe", and "good". It is saying that the verse draws attention to "song" and "degrees", so its meaning should be read from those terms before moving to application.
The local GNV text gives this verse as the immediate unit, so "song" and "degrees" carries the first interpretive weight. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "song" and "degrees" with trust shaped by these words, not by a vague optimism outside the passage.
