'Day of the Lord' in the Bible

For that day is a day of the Lord, Jehovah of hosts, a day of vengeance, that he may avenge him of his adversaries: and the sword shall devour and be satiate, and shall drink its fill of their blood; for the Lord, Jehovah of hosts, hath a sacrifice in the north country by the river Euphrates.

The sun shall be turned into darkness, And the moon into blood, Before the day of the Lord come, That great and notable day .

to deliver such a one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.

For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.

to the end that ye be not quickly shaken from your mind, nor yet be troubled, either by spirit, or by word, or by epistle as from us, as that the day of the Lord is just at hand;

But the day of the Lord will come as a thief; in the which the heavens shall pass away with a great noise, and the elements shall be dissolved with fervent heat, and the earth and the works that are therein shall be burned up.
