'In that Day' in the Bible

Look, like an eagle he will go up and he will swoop down, and he will spread out his wings against Bozrah. And the heart of the warriors of Edom will be in that day like [the] heart of a woman [who] is in labor.

{Therefore} her young men will fall in her public squares, and all {the soldiers} will perish in that day," {declares} Yahweh of hosts.
