The historical placement of Jeremiah's early ministry: Jeremiah became a Prophet and began to prophesy in the 13th year of the reign of Josiah which was 5 years after Josiah began to seek after the God of David his father (2 Chron. 34:3). This first 4 years of seeking the LORD and 1 year of purging the Land which transpired before Jeremiah became a Prophet is relevant to the Tribulation Period. My reader Josiah was not alone.
