‘Though you are high, you care for the lowly.’ (6)
Verse 1 in this psalm of praise imagines God sitting supreme in the company of other gods and lesser heavenly beings. Literal or figurative, this sketch has the potential for a “head-of-a-pin” side track discussion about angels and gods. Not my thing.
So concentrate on the remaining message — which essentially is that we should adhere to (“bow towards the holy temple of”) love and faithfulness. God holds these above all things. (2)
In such a régime, the rulers of the world would listen to the divinely ordained ethical structure, the ‘word’ of Psalm 119. (4)
They would provide leadership to implement these principles. It’s not much use just praising them without action.

Then, this gracious influence will preserve and enhance the potential in each and every one. (7) The psalmist concludes with a prayer that the divine Spirit would sustain this work of love in our lives and world. (8)

Delightful early music settings are to be found under various headings, corresponding to various verse selections of the psalm and the various languages of the composers.

Some years ago I arranged this refrain for four voices, then paraphrased the verses to fit the same tune with an additional contrasting B section in an AABA. The four part harmony is definitely not happening, but for interest, here’s the refrain:
