Shelter and plague
The psalm speaks of dwelling in the secret place, of pinions and fortress, of pestilence and terror by night (Psalm 91:1–8). It is temple and wilderness language: safety is location in God, not a lucky object. Verses 9–16 shift to divine speech: I will deliver, protect, and show my salvation.
Matthew Henry’s Commentary · Matthew Henry
Henry reads the psalm as the privilege of those who make God their habitation, not as a charm against every earthly harm for the careless.
How Satan quoted it
In the wilderness the devil quotes Psalm 91:11–12 to urge Jesus to jump (Matthew 4:5–7). Jesus answers with “Do not put the Lord to the test.” The psalm is not a license for spectacle. Some Christians have treated 91 as a guarantee against all illness; the rest of Scripture (Job, the Passion, 2 Timothy 4:20) will not bear that.
Jamieson-Fausset-Brown Bible Commentary · JFB
JFB on Matthew 4 note that Satan omits “in all your ways,” twisting a promise of keeping into a dare.
