'Day of the Lord' in the Bible

Remain silent in the presence of the Lord GOD, because the Day of the LORD approaches, and because the LORD has prepared a sacrifice for those whom he has invited to be consecrated.

"The great Day of the LORD approaches How it comes, hurrying faster and faster! The sound of the Day of the LORD there includes the bitter cry of the mighty soldier.

Neither their silver nor their gold will deliver them in the Day of the LORD's wrath; but the entire land will be consumed by the fire of his jealousy, for he will bring the inhabitants of the land to a sudden end."

Before the decree is carried out, before the day flies away like chaff, before the fierce anger of the LORD visits you, before the Day of the LORD's wrath surprises you,

seek the LORD, all you humble people of the land, who do what he commands. Seek righteousness! Seek humility! Maybe you will be protected in the Day of the LORD's anger."
