The discrepancy between the length of the siege according to the regnal years of Zedekiah (years 9-11), on the one hand, and its length according to Jehoiachin's exile (years 9-12), on the other, can be cancelled out only by supposing the former to have been reckoned on a Tishri basis, and the latter on a Nisan basis. The difference of one year between the two is accounted for by the fact that the termination of the siege fell in the summer, between Nisan and Tishri, already in the 12th year according to the reckoning in Ezekiel, but still in Zedekiah's 11th year which was to end only in Tishri.
