Passage
He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.
He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.
Psalms 91:1 He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.
Psalms 91:2 I will say of the LORD, He is my refuge and my fortress: my God; in him will I trust.
Psalms 91:3 Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.
The verse centers on "dwelleth", "secret", "place", "most", "high", "shall", "abide", and "under". It is saying that the verse draws attention to "dwelleth" and "secret", so its meaning should be read from those terms before moving to application.
The next verse adds "I will say of the LORD He...", so "dwelleth" and "secret" should be read forward into that movement. 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 "dwelleth" and "secret" with trust shaped by these words, not by a vague optimism outside the passage.
