132:1 A gradual canticle of David. Behold how good and how pleasant it is for brethren to dwell together in unity:
132:2 Like the precious ointment on the head, that ran down upon the beard, the beard of Aaron, Which ran down to the skirt of his garment:
132:3 As the dew of Hermon, which descendeth upon mount Sion. For there the Lord hath commanded blessing, and life for evermore.
The verse centers on "gradual", "canticle", "david", "behold", "good", "pleasant", "brethren", and "dwell". It is saying that the verse draws attention to "gradual" and "canticle", so its meaning should be read from those terms before moving to application.
The local DRB text gives this verse as the immediate unit, so "gradual" and "canticle" 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 "gradual" and "canticle" with trust shaped by these words, not by a vague optimism outside the passage.
