Psalms 91:3

“Surely he shall deliver thee from the snare of the fowler, etc.] These are the words of the psalmist, either speaking to himself, for the encouragement of his own faith and trust in the Lord; or to the man that dwells in the secret place, and under the shadow of the most High; which latter seems most agreeable; though Cocceius thinks they are the words of God in one of his Persons, speaking of another divine Person that should deliver such that trust in him: the Targum makes them to be the words of David to Solomon his son. By the “fowler” and his “snare” may be meant either Saul, who laid wait for David, spread snares for him, and hunted him as a partridge on the mountains, from whom he was…”

“Surely he shall deliver thee from the snare of the fowler - The snare or gin set for catching birds; meaning, here, that God would save him from the purposes of wicked people; such purposes as might be compared with the devices employed to catch birds. On the meaning of the figure used here, see the notes at Psalms 18:5. And from the noisome pestilence - The “fatal” pestilence; the pestilence that spreads death in its march. That is, he can prevent its coming upon you; or, he can save you from its ravages, while others are dying around you. This promise is not to be understood as absolute, or as meaning that no one who fears God will ever fall by the pestilence - for good people “do” die at…”

“Pestilence - From the pestilence, which like a fowler's snare takes men suddenly and unexpectedly. Psalms 91:5”

“91:3-4 The psalmist invites the godly to trust in the Lord and find protection in him. 91:3 God protects the godly from deadly disease and even a destructive word.”

“snare: Psa 124:7, Psa 141:9; Pro 7:23; Ecc 9:12; Hos 9:8; Amo 3:5; Ti1 6:9; Ti2 2:26 and from: Psa 91:6; Num 14:37, Num 14:38, Num 16:46-48; Sa2 24:15; Job 5:10-22 Psalms 91:4”

“יקושׁ, as in Pro 6:5; Jer 5:26, is the dullest toned from for יקושׁ or יוקשׁ, Psa 124:7. What is meant is death, or "he who has the power of death," Heb 2:14, cf. Ti2 2:26. "The snare of the fowler" is a figure for the peril of one's life, Ecc 9:12. In connection with Psa 91:4 we have to call to mind Deu 32:11 : God protects His own as an eagle with its large strong wing. אברה is nom. unitatis, a pinion, to אבר, Isa 40:31; and the Hiph. הסך, from סכך, with the dative of the object, like the Kal in Psa 140:8, signifies to afford covering, protection. The ἅπαξ λεγ. סחרה, according to its stem-word, is that which encompasses anything round about, and here beside צנּה, a weapon of defence…”
