2 Kings 25:1-2

1Nebuchadnezzar, the king of Babylon, marched with all his army to attack Jerusalem. He arrived on the 10th day of the 10th month, in the 9th year when Zedekiah had ruled Judah. His soldiers made their camp all around the city. They built heaps of earth all around Jerusalem's walls.

2Babylon's army stayed around the city until the 11th year that Zedekiah had been king.
