Under the form of this strong prohibition there is an equally strong promise. So safe will all thy ways be that to fear will be a sin.

(l) Be not afraid of sudden fear, neither of the desolation of the wicked, when it cometh.
(l) For when God destroys the wicked he will save his as he did Lot in Sodom.

Be not afraid of sudden fear,.... Of anything terrible that comes unawares, unthought of, by any of the above things mentioned in the preceding note; or by any rumours and reports of danger being near at hand; always think thyself safe in the arms of Wisdom, and under the care of Israel's keeper, who neither slumbers nor sleeps;
neither of the desolation of the wicked when it cometh; either of the desolation which wicked men threaten to bring, and are suffered to bring, upon the godly for the sake of religion; either on their persons or goods, since suffering at their hands in such a cause is to the honour of saints, and for the glory of God; or of the desolation which comes upon the godly, for God is able to deliver him from it, as Noah and his family from the universal deluge, and Lot and his family from Sodom and Gomorrah; or if they promiscuously fall in it, nevertheless it will be well with them to all eternity.

Be not--or, "You shall not be."
sudden fear--what causes it (Proverbs 1:27), any unlooked-for evil (Psalm 46:3; Psalm 91:12; 1-Peter 3:14).
desolation-- (Proverbs 1:27).

Be not - Thou shalt not be afraid. Sudden - For sudden and unexpected evils are most frightful. And fear is here put for the evils feared. Desolation - Which cometh upon the wicked.
