'In that Day' in the Bible

And it will come about in that day, says the Lord, that the heart of the king will be dead in him, and the hearts of the rulers; and the priests will be overcome with fear, and the prophets with wonder.

Kerioth is taken, and the strong places have been forced, and the hearts of Moab's men of war in that day will be like the heart of a woman in birth-pains.

So her young men will be falling in her streets, and all the men of war will be cut off in that day, says the Lord of armies.

For this cause her young men will be falling in her streets, and all her men of war will be cut off in that day, says the Lord.
