Jeremiah 39:1-2
Context39:1 King Nebuchadnezzar of Babylon came against Jerusalem with his whole army and laid siege to it. The siege began in the tenth month of the ninth year that Zedekiah ruled over Judah. 1 39:2 It lasted until the ninth day of the fourth month of Zedekiah’s eleventh year. 2 On that day they broke through the city walls.
1 sn 2 Kgs 25:1 and Jer 52:4 give the more precise date of the tenth day of the tenth month of the ninth year which would have been Jan 15, 588
2 sn According to modern reckoning that would have been July 18, 586
