'In that Day' in the Bible

"And the songs of the temple shall become wailings in that day," {declares} my Lord Yahweh. "The corpses are numerous; he throws them in every place. Be quiet!"

And then in that day," {declares} my Lord Yahweh, "I will make the sun go down at noon and I will darken the land on a day of light.

In that day the beautiful young women and the young men will faint because of thirst.
