'Day' in the Bible

"Won't I in that day," says Yahweh, "destroy the wise men out of Edom, and understanding out of the mountain of Esau?

In the day that you stood on the other side, in the day that strangers carried away his substance, and foreigners entered into his gates, and cast lots for Jerusalem, even you were like one of them.

But don't look down on your brother in the day of his disaster, and don't rejoice over the children of Judah in the day of their destruction. Don't speak proudly in the day of distress.

Don't enter into the gate of my people in the day of their calamity. Don't look down on their affliction in the day of their calamity, neither seize their wealth on the day of their calamity.

Don't stand in the crossroads to cut off those of his who escape. Don't deliver up those of his who remain in the day of distress.

For the day of Yahweh is near all the nations! As you have done, it will be done to you. Your deeds will return upon your own head.
