Jeremiah 39:2

The siege lasted a year and half, for it was the fourth month of Zedekiah's eleventh year before it was taken: it is said here to be broken up, because their way of taking fortified places then was by beating down the walls of the besieged with iron rams and engines, as we now do with great guns. This kingdom had now held three hundred and eighty years, from Rehoboam their first king, in which they had had twenty kings (besides Athaliah). The ten tribes had been now in captivity one hundred and thirty years, so as the kingdom of Israel stood but two hundred and fifty years after the division, in which time they had had eighteen princes, but of several families; all the kings of Judah were of the house of David, lineally descended from him.
