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:
For the day of the Lord of hosts (shall be) upon every (one that is) proud. 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" (1 Corinthians 15:28; 2 Peter 3:10).
Every - not merely person, as the English version explains it, but every thing on which the nation prided itself.
