'Day of the Lord' in the Bible

"On the day of the Lord's sacrificial meal, I will punish the princes and the king's sons, and all who wear foreign styles of clothing.

Neither their silver nor their gold will be able to deliver them in the day of the Lord's angry judgment. The whole earth will be consumed by his fiery wrath. Indeed, he will bring terrifying destruction on all who live on the earth."

before God's decree becomes reality and the day of opportunity disappears like windblown chaff, before the Lord's raging anger overtakes you -- before the day of the Lord's angry judgment overtakes you!

Seek the Lord's favor, all you humble people of the land who have obeyed his commands! Strive to do what is right! Strive to be humble! Maybe you will be protected on the day of the Lord's angry judgment.
