'Day' in the Bible

Is it not in that day -- an affirmation of Jehovah, That I have destroyed the wise out of Edom, And understanding out of the mount of Esau?

In the day of thy standing over-against, In the day of strangers taking captive his force, And foreigners have entered his gates, And for Jerusalem have cast a lot, Even thou art as one of them!

And -- thou dost not look on the day of thy brother, On the day of his alienation, Nor dost thou rejoice over sons of Judah, In the day of their destruction, Nor make great thy mouth in a day of distress.

Nor come into a gate of My people in a day of their calamity, Nor look, even thou, on its misfortune in a day of its calamity, Nor send forth against its force in a day of its calamity,

Nor stand by the breach to cut off its escaped, Nor deliver up its remnant in a day of distress.

For near is the day of Jehovah, on all the nations, As thou hast done, it is done to thee, Thy deed doth turn back on thine own head.
