Isaiah 2:12

“For the day of the Lord of hosts, &c.] Which is peculiarly his, which he has fixed and appointed, and in which there will be a great display of the glory of his power and grace: this [shall be] upon every [one that is] proud and lofty, and upon every [one that is] lifted up, and he shall be brought low; either the day of his mighty power and efficacious grace shall be upon them to convert them; when they who thought themselves in a good estate, rich, and standing in need of nothing, shall now perceive themselves to be in a very poor, wretched, and miserable one; and when such who have trusted in and boasted of their own righteousness, and despised others, and would not submit to the…”

“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" (Co1 15:28; Pe2 3:10). every--not merely person, as English Version explains it, but every thing on which the nation prided itself.”

“The expression "that day" suggests the inquiry, What day is referred to? The prophet answers this question in the second strophe. "For Jehovah of hosts hath a day over everything towering and lofty, and over everything exalted; and it becomes low." "Jehovah hath a day" (yom layehovah), lit., there is to Jehovah a day, which already exists as a finished divine thought in that wisdom by which the course of history is guided ( Isa 37:26, cf., Isa 22:11), the secret of which He revealed to the prophets, who from the time of Obadiah and Joel downwards proclaimed that day with one uniform watchword.
