'On that Day' in the Bible

“On that day they will take up against you a tauntAnd utter a bitter lamentation and say,‘We are completely destroyed!He exchanges the portion of my people;How He removes it from me!To the apostate He apportions our fields.’

On that day—this is the Lord’s declaration—I will assemble the lameand gather the scattered,those I have injured.

In the day when thy walls shall be built, on that day shall the established limit recede.

On that day people will come to youfrom Assyria and the cities of Egypt,even from Egypt to the Euphrates Riverand from sea to seaand mountain to mountain.
