Psalm 91 redux

I was looking at the NET Bible online and found that their text and notes for Psalm 91 offer up a possible explanation for the structure of verses 1-2 that I discussed below. First, verses 1-3 in the NET translation:

As for you, the one who lives in the shelter of the sovereign One, and resides in the protective shadow of the mighty king – I say this about the Lord, my shelter and my stronghold, my God in whom I trust – he will certainly rescue you from the snare of the hunter and from the destructive plague.

In this translation, verse 2 (”I say this…”) is set apart from the text as an aside from the narrator, while vss 1 and 3 use the second-person “you” to speak to the reader. The footnotes state that in “this psalm an individual (perhaps a priest) addresses one who has sought shelter in the Lord and assures him that God will protect him from danger.” If this is the case, then none of the primary translations I considered really hit the mark. The NLTse and HCSB make the switch to first-person in v2, but these opening passages still remain an odd jumble of first-, second- and third-person voices. The NET is consistent between v1 and the rest of the psalm, and uses effective structural markers to set v2 apart.
