John Gill Commentary Proverbs 1:27

"When your fear cometh as a storm, And your calamity cometh on as a whirlwind; When distress and anguish come upon you." — Proverbs 1:27 (ASV)

When your fear comes as desolation

When such will be the calamity that will occasion this fear, that it shall be like some desolating judgment, as famine, sword, and pestilence, which lays all waste: and such was the destruction of the Jews by the Romans; it not only laid Jerusalem and the temple waste, but the whole country of Judea. These are the "desolations" said to be "determined", or "the consummation and that determined", which should be "poured upon the desolate", (Daniel 9:26Daniel 9:27) ;

and your destruction comes as a whirlwind

suddenly and unthought of, fierce, and boisterous, throwing down and carrying all before it: so the said destruction did; it threw down the walls and houses of the city of Jerusalem, and the temple, and its fine buildings, so that not one stone was left upon another not thrown down, (Matthew 24:2) ;

when distress and anguish comes upon you

as they did at that time with a witness, when Jerusalem was besieged by the Romans: what with the sword of the enemy without, and the famine within; together with the vast number of cutthroats and seditious persons among themselves; it was such a time of distress and tribulation as never was from the beginning of the world, nor ever will be, (Matthew 24:22) . Josephus's history of those times is a proper comment on these words.
