2 This I declare about the Lord : He alone is my refuge, my place of safety; he is my God, and I trust him. 3 For he will rescue you from every trap and protect you from deadly disease. 4 He will cover you with his feathers. He will shelter you with his wings. His faithful promises are your armor and protection. 5 Do not be afraid of the terrors of the night, nor the arrow that flies in the day. 6 Do not dread the disease that stalks in darkness, nor the disaster that strikes at midday. 7 Though a thousand fall at your side, though ten thousand are dying around you, these evils will not touch you.
Matthew Henry's Commentary on Psalm 91:2-7
Commentary on Psalm 91:1-8
(Read Psalm 91:1-8)
He that by faith chooses God for his protector, shall find all in him that he needs or can desire. And those who have found the comfort of making the Lord their refuge, cannot but desire that others may do so. The spiritual life is protected by Divine grace from the temptations of Satan, which are as the snares of the fowler, and from the contagion of sin, which is a noisome pestilence. Great security is promised to believers in the midst of danger. Wisdom shall keep them from being afraid without cause, and faith shall keep them from being unduly afraid. Whatever is done, our heavenly Father's will is done; and we have no reason to fear. God's people shall see, not only God's promises fulfilled, but his threatenings. Then let sinners come unto the Lord upon his mercy-seat, through the Redeemer's name; and encourage others to trust in him also.
