For starters, 5, 59639 has direct secular evidence and the biblical narrative to support this date as the fall of Babylon, the fall of Jerusalem also has many scriptures which fod and described the event similar to Babylons. fall. The main difference between the fall of both cities is that there is no direct secular evidence for Jerusalem as there is with Babylon. The fall of Jerusalem can only be calculated with scripture only with a secular fixed date which is not the same with the calculation of Bavylon. In short, it is only the fall of Babylon that that has an independent chronological base. For this reason the fall of Jerusalem is not regardeda as a absolute or pivtal date as with the fall of Babylon in 539. Also, this is the reason why scholars cannot determine whether it is 586 or 587 for Jerusalem' fall. The society under the guidance of holy spirit and holy writ has determined that 607 is the only possible choice and we can all thank Jehovah and his Son for this amazing understabding.
