'Day' in the Bible

In that day—this is the Lord’s declaration—will I not eliminate the wise ones of Edomand those who understandfrom the hill country of Esau?

On the day you stood aloof,on the day strangers captured his wealth,while foreigners entered his gateand cast lots for Jerusalem,you were just like one of them.

Do not gloat over your brotherin the day of his calamity;do not rejoice over the people of Judahin the day of their destruction;do not boastfully mockin the day of distress.

Do not enter the gate of My peoplein the day of their disaster.Yes, you—do not gloat over their miseryin the day of their disasterand do not appropriate their possessionsin the day of their disaster.

Do not stand at the crossroadsto cut off their fugitives,and do not hand over their survivorsin the day of distress.

For the Day of the Lord is near,against all the nations.As you have done, so it will be done to you;what you deserve will return on your own head.
