Jeremiah 52:4

And it came to pass in the ninth year of his reign ,.... Of Zedekiah's reign:

in the tenth month, in the tenth day of the month ; the month Tebet, which answers to part of December and part of January; hence the fast of the tenth month, on account of the siege of Jerusalem, Zechariah 8:19 ;

that Nebuchadrezzar king of Babylon came, he, and all his army ,

against Jerusalem ; from whence it appears that he came in person with his army at first to Jerusalem; but, during the siege, or some part of it, retired to Riblah; perhaps upon the news of the king of Egypt's coming to the assistance of the Jews:

and pitched against it ; or encamped against it:

and built forts against it round about ; wooden towers, as Jarchi and Kimchi explain it; from whence they could shoot their arrows and cast their stones.
