Thou shalt not be afraid for the terror by night - That which usually causes alarm at night - a sudden attack; an unexpected incursion of enemies; sudden disease coming on by night; or the pestilence which seems to love night, and to "walk in darkness." Any one of these things seems to be aggravated by night and darkness; and hence, we most dread them then. We cannot see their approach; we cannot measure their outlines; we know not the extent of the danger, or what may be the calamity.

Nor for the arrow that flieth by day - Whether shot from the bow of God - as pestilence and disease; or from the hand of man in battle. The idea is, that he that trusts in God will be calm. Compare the notes at Psalm 56:3.

The terror by night - Night is a time of terrors, because it is a time of treasons, plunder, robbery, and murder. The godly man lies down in peace, and sleeps quietly, for he trusts his body, soul, and substance, in the hand of God; and he knows that he who keepeth Israel neither slumbers nor sleeps. It may also mean all spiritual foes, - the rulers of the darkness of this world. I have heard the following petition in an evening family prayer: "Blessed Lord, take us into thy protection this night; and preserve us from disease, from sudden death, from the violence of fire, from the edge of the sword, from the designs of wicked men, and from the influence of malicious spirits!"

Nor for the arrow - The Chaldee translates this verse, "Thou shalt not fear the demons that walk by night; nor the arrow of the angel of death which is shot in the day time." Thou needest not to fear a sudden and unprovided-for death.

Thou shalt not be afraid for the terror by night,.... The terrible things that happen in the night; as fire, storms and tempests, invasion of enemies, murders, thefts, and, robberies: a good man, when he has committed himself and his family to the care and protection of God by prayer, has no reason to be anxiously careful of these things, or to indulge a slavish fear about them; see Psalm 3:5, the Targum is,

"thou shall not be afraid for the fear of devils that walk in the night:''

so Jarchi interprets this, and the next verse, of such; as do others of the Jewish writers: a man that trusts in the Lord need not be afraid of men or devils: a fear of evil spirits is natural to men, and very early appeared; perhaps it took its rise from the fatal affair of the fall of our first parents, through an intercourse with an evil spirit; and ever since has been imprinted on human nature an aversion to evil spirits, and a dread of them, and even of all spirits in general; see Job 4:13,

nor for the arrow that flieth by day; the judgments of God, such as the sword, famine, and pestilence; these are called the arrows of God, Deuteronomy 32:23 (q), because they move swiftly, come suddenly, and strike surely, and are open and visible; they are sent by the Lord, and are ordered and directed by him, and hit and hurt whom he pleases, and none else; and therefore such who dwell in the secret of the Lord, and under his shadow, need not be distressed about them: the Targum interprets it of the arrow of the angel of death, which he sends out in the day; see Hebrews 2:14, so Jarchi understands it of a demon that flies like an arrow.

(q) ---- , Homer. Iliad. 1. v. 51, 53.

{e} Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day;

(e) The care that God has over his is sufficient to defend them from all dangers.

91:5 By night - When evil accidents are most terrible and least avoidable. Arrow - The pestilence, or any such destructive calamity; such are frequently called God's arrows. By day - Thou shalt be kept from secret and open mischiefs.

5. terror-or, what causes it (Pr 20:2).

by night-then aggravated.

arrow-that is, of enemies.

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.
