Jacob had his trouble when Christ came the first time. I don't see 2 times of Jacob's trouble in the bible.
Luke 21:22 For these be the days of vengeance, that all things which are written may be fulfilled.
Above is the context of 70ad when the days of vengeance began.
Whereas, the time of Jacob’s trouble is at the end, and out of which trouble a remnant shall be saved.
Jeremiah 30:7 Alas! 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.
8 For 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:
9 But they shall serve the LORD their God, and David their king, whom I will raise up unto them.
10 Therefore fear thou not, O my servant Jacob, saith the LORD; neither be dismayed, O Israel: for, lo, I will save thee from afar, and thy seed from the land of their captivity; and Jacob shall return, and shall be in rest, and be quiet, and none shall make him afraid.
11 For I am with thee, saith the LORD, to save thee: though I make a full end of all nations whither I have scattered thee, yet will I not make a full end of thee: but I will correct thee in measure, and will not leave thee altogether unpunished.
