At that time
When Jehoiachin reigned:
when the year was expired;
so it is in ( 2 Chronicles 36:10 ) or at the revolution of the year; which some take to be autumn, the beginning of the civil year with the Jews; but rather it was the spring, the time when kings went out to battle, ( 2 Samuel 11:1 )
the servants of Nebuchadnezzar king of Babylon came up against
that is, his army, under proper generals and officers, and by his orders:
and the city was besieged;
in form by the Chaldean army.
