'Day of the Lord' in the Bible

For there will be a day of the LORD of hosts for all that is proud and haughty, and for all that is lifted up; and it shall be brought low:

Wail; for the day of the LORD is at hand. It will come as destruction from Shaddai.

Behold, the day of the LORD comes, cruel, with wrath and fierce anger; to make the land a desolation, and to destroy its sinners out of it.
