Psalm 91:3
3 [...] the Psalmist expresses his assurance that the trust of which he had spoken would not be vain and delusory, but that God would prove at all times the deliverer of his people. He is evidently to be considered as addressing himself, and in this way encouraging his own heart to hope in the Lord. Some think that by the snare of the fowler, spoken of here in connection with the pestilence, is to be understood hidden mischief as distinguished from open aggression, and that the Psalmist declares the Divine protection to be sufficient for him, whether Satan should attack him openly and violently or by more secret and subtle methods. I would not reject this interpretation; for though some may think that the words should be taken in their simpler acceptation, the Psalmist most probably intended under these terms to denote all different kinds of evil, and to teach us that God was willing and able to deliver us from any of them.
Psalm 91:5
5 Thou shalt not fear for the terror of the night. The Psalmist continues to insist upon the truth which I have just adverted to, that, if we confide with implicit reliance upon the protection of God, we will be secure from every temptation and assault of Satan. It is of importance to remember, that those whom God has taken under his care are in a state of the most absolute safety. Even those who have reached the most advanced experience find nothing more difficult than to rely upon Divine deliverance; and more especially when, overtaken by some of the many forms in which danger and death await us in this world, doubts will insinuate themselves into our hearts, giving rise to fear and disquietude. There was reason, therefore, why the Psalmist should enter upon a specification of different evils, encouraging the Lord’s people to look for more than one mode of deliverance, and to bear up under various and accumulated calamities. Mention is made of the fear of the night, because men are naturally apprehensive in the dark, or because the night exposes us to dangers of different kinds, and our fears are apt at such a season to magnify any sound or disturbance. The arrow, rather than another weapon, is instanced as flying by day, for the reason apparently that it shoots to a greater distance, and with such swiftness, that we can with difficulty escape it. The verse which follows states, though in different words, the same truth, that there is no kind of calamity which the shield of the Almighty cannot ward off and repel.
Psalm 91:11
[...]
The Psalmist, in the passage now before us, speaks of members of the Church generally; and yet the devil did not wrest the words when, in his temptation in the wilderness, he applied them particularly to Christ. It is true that he is constantly seeking to pervert and corrupt the truth of God; but, so far as general principles are concerned, he can put a specious gloss upon things, and is a sufficiently acute theologian. It is to be considered that when our whole human family were banished from the Divine favor, we ceased to have anything in common with the angels, and they to have any communication with us. It was Christ, and he only, who, by removing the ground of separation, reconciled the angels to us; this being his proper office, as the apostle observes, (
Ephesians 1:10,) to gather together in one what had been dispersed both in heaven and on earth. This was represented to the holy patriarch Jacob under the figure of a ladder, (
Genesis 28:12;) and, in allusion to our being united into one collective body with the angels, Christ said,
“Afterwards ye shall see the heavens opened, and the angels of God ascending and descending,” (
John 1:51.)
