For the day of the LORD of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up; and he shall be brought low:

Jamieson-Fausset-Brown Bible Commentary

12. Man has had many days: "the day of the Lord" shall come at last, beginning with judgment, a never-ending day in which God shall be "all in all" (1Co 15:28; 2Pe 3:10).

every-not merely person, as English Version explains it, but every thing on which the nation prided itself.

Matthew Henry's Concise Commentary

2:10-22 The taking of Jerusalem by the Chaldeans seems first meant here, when idolatry among the Jews was done away; but our thoughts are led forward to the destruction of all the enemies of Christ. It is folly for those who are pursued by the wrath of God, to think to hide or shelter themselves from it. The shaking of the earth will be terrible to those who set their affections on things of the earth. Men's haughtiness will be brought down, either by the grace of God convincing them of the evil of pride, or by the providence of God depriving them of all the things they were proud of. The day of the Lord shall be upon those things in which they put their confidence. Those who will not be reasoned out of their sins, sooner or later shall be frightened out of them. Covetous men make money their god; but the time will come when they will feel it as much their burden. This whole passage may be applied to the case of an awakened sinner, ready to leave all that his soul may be saved. The Jews were prone to rely on their heathen neighbours; but they are here called upon to cease from depending on mortal man. We are all prone to the same sin. Then let not man be your fear, let not him be your hope; but let your hope be in the Lord your God. Let us make this our great concern.
