most copies gave 190 years. these numbers fits in with the thought that Ezekiel's act was to represent the period of the punishment of the northern kingdom. That punishment starts from the first captivity under Pekah about B.C. 734. Reckoning from that date, the 190 years bring us to about B.C. 544. The punishment of Judah, dates from the destruction of Jerusalem in B.C. 586, and the forty years bring us to B.C. 546, a date so near the other, that they may be taken as practically coinciding. It was to that date that the prophet, perhaps, unacquainted with Jeremiah's seventy years (Jeremiah 25:12), with a different starting point ( B.C. 600) and terminus ( B.C. 536), looked forward as the starting point of the restoration of Israel
