““The siege of Jerusalem lasted only two years, and it’s clear from Jeremiah’s prophecies that Nebuchadnezzar’s army was not only attacking Jerusalem itself but several of the fortified cities of Judah that were supporting it: “…the army of the king of Babylon was fighting against Jerusalem and against all the cities of Judah that were left, Lachish and Azekah; for these were the only fortified cities of Judah that remained.” (Jer. 34:7). Archaeological finds also indicate that the Babylonians also destroyed the Judean towns of Beth Shemesh, Gezer, and Tell el-Hesi at this time. ””
