Jehovah witness dating a non believer
See the translator’s note on Jeremiah 25:1 for the method of dating a king’s reign." (NET Note) Charles Dyer has a detailed note on the dating of this passage - The 10th year of Zedekiah would have ended on October 17, 587 B. (using the Judean Tishri-to-Tishri year) while the 18th year of Nebuchadnezzar began on April 23, 587 (using the Babylonian Nisan-to-Nisan year).Thus this prophecy occurred sometime between April 23 and October 17, 587 B. During this time Babylon was besieging Jerusalem-a siege that lasted from January 15, 588 till July 18, 586-and Jeremiah was under arrest and confined in the palace courtyard of the guard.3 Yet King Zedekiah sent Jehucal the son of Shelemiah, and Zephaniah the son of Maaseiah, the priest, to Jeremiah the prophet, saying, “Please pray to the LORD our God on our behalf.” 4 Now Jeremiah was still coming in and going out among the people (: He had freedom of movement in the city), for they had not yet put him in the prison.5 Meanwhile, Pharaoh’s army had set out from Egypt; and when the Chaldeans who had been besieging Jerusalem heard the report about them, they lifted the siege from Jerusalem.Stated another way this would be about 587 BC or about one year left in the final siege of Jerusalem.
Tenth year of Zedekiah king of Judah (about 587BC) - From comparison of 2Ki 25:1-2 and Jer 39:1-2 below we can deduce that the word of the LORD came to Jeremiah in roughly the middle of Nebuchadnezzar's approximately 3 year siege of Jerusalem.After appealing to Zedekiah he had been moved from the dungeon to the courtyard of the guardhouse connected to the palace (Jer ) where he remained confined until Jerusalem was captured in 587/86 B. KJV For then the king of Babylon's army besieged Jerusalem: and Jeremiah the prophet was shut up in the court of the prison, which was in the king of Judah's house.ESV At that time the army of the king of Babylon was besieging Jerusalem, and Jeremiah the prophet was shut up in the court of the guard that was in the palace of the king of Judah.Now Zedekiah the son of Josiah whom Nebuchadnezzar king of Babylon had made king in the land of Judah, reigned as king in place of Coniah the son of Jehoiakim.2 But neither he nor his servants nor the people of the land listened to the words of the LORD which He spoke through Jeremiah the prophet.
