2 Kings 25:1 (KJV)
1 And it came to pass in the ninth year of his reign, in the tenth month, in the tenth day of the month, that Nebuchadnezzar king of Babylon came, he, and all his host, against Jerusalem, and pitched against it: and they built forts against it round about. 2 And the city was besieged unto the eleventh year of king Zedekiah.
2 Kings 25:8 (KJV)
8 And in the fifth month, on the seventh day of the month, which is the nineteenth year of king Nebuchadnezzar king of Babylon, came Nebuzaradan, captain of the guard, a servant of the king of Babylon, unto Jerusalem: 9 And he burnt the house of the LORD, and the king's house, and all the houses of Jerusalem, and every great man's house burnt he with fire.
One raid seems to be led by king Nebuchnezzar who takes Zedekiah to Babylon & the other led by captain of the guard Nebuzaradan who takes Seraiah the chief priest & Zephaniah the second priest, who seem to have been left in the first raid.
Are these two different raids of Jerusalem or one continuous siege?
