Psalms 91:5

“Thou shalt not be afraid for the terror by night, etc.] 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 <190305>Psalm 3:5 4:8 <200324>Proverbs 3:24,25), 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…”

“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…”

“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. Psalms 91:6”

“91:5-8 The godly should not be afraid, because the Lord watches over them. These promises do not guarantee an escape from trouble, but they create an expectation of the Lord’s goodness.”
