The Time of Jacob’s Troubles describes the second half of Daniel’s 70th week or the Tribulation. It is described as the most intense period in the history of the world. The world has never seen this distress ever.
JEREMIAH 30:7- ALAS! THAT DAY IS SO GREAT THERE IS NONE LIKE IT; IT IS A TIME OF DISTRESS FOR JACOB; YET HE SHALL BE SAVED OUT OF IT.
