A time of trouble such as never there was

"Jeremiah 30 3For, lo, the days come, saith the LORD, that I will bring again the captivity of my people Israel and Judah, saith the LORD: and I will cause them to return to the land that I gave to their fathers, and they shall possess it. 4And these are the words that the LORD spake concerning Israel and concerning Judah. 5For thus saith the LORD; We have heard a voice of trembling, of fear, and not of peace. 6Ask ye now, and see whether a man doth travail with child? wherefore do I see every man with his hands on his loins, as a woman in travail, and all faces are turned into paleness? 7Alas! for that day is great, so that none is like it: it is even the time of Jacob's trouble; but he shall be saved out of it. 8For it shall come to pass in that day, saith the LORD of hosts, that I will break his yoke from off thy neck, and will burst thy bonds, and strangers shall no more serve themselves of him: 9But they shall serve the LORD their God, and David their king, whom I will raise up unto them."
