Q. Jeremiah 1:13 and 1:14 says that the evil would come from the north. Who represents the north today and has that happened yet?
The problem we have in understanding such questions is understanding the time of the fulfillment of these prophecies. Many people attempt to find the fulfillment of the prophecies at the end of time. Actually this prophecy in Jeremiah is a reference to Babylon attacking and destroying Jerusalem. This took place in approximately 606 BC. Jeremiah prophesied just prior to, and during the destruction of Jerusalem. His message to Israel was: Turn back to God or be punished. They were eventually taken captive by the Babylonian empire. Daniel prophesied during this period of captivity.
There is an interesting statement in the book of Daniel concerning the prophecies of Jeremiah.
Dan 9:2 says, In the first year of his reign I Daniel understood by books the number of the years, whereof the word of the LORD came to Jeremiah the prophet, that he would accomplish seventy years in the desolations of Jerusalem.
Daniel read the prophecies of Jeremiah and understood that the appointed 70 years of Babylonian captivity were completed. He then prayed to the Lord that the people would once again be returned to Jerusalem.
