Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.
Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.
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.
Psalms 91:4 He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler.
Psalms 91:5 Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day;
The verse centers on "surely", "shall", "deliver", "thee", "snare", "fowler", "noisome", and "pestilence". It is saying that the verse draws attention to "surely" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "I will say of the LORD He..." into verse 4's "He shall cover thee with his feathers...", so "surely" and "shall" belong inside that flow. 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 "surely" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
