'Day of the Lord' in the Bible

Woe because of that day!For the Day of the Lord is nearand will come as devastation from the Almighty.

Blow the horn in Zion;sound the alarm on My holy mountain!Let all the residents of the land tremble,for the Day of the Lord is coming;in fact, it is near—

The Lord raises His voicein the presence of His army.His camp is very large;Those who carry out His command are powerful.Indeed, the Day of the Lord is terrible and dreadful—who can endure it?

The sun will be turned to darknessand the moon to bloodbefore the great and awe-inspiring Day of the Lord comes.

Multitudes, multitudesin the valley of decision!For the Day of the Lord is nearin the valley of decision.
