Daniel 9:24 Seventy weeks are determined upon thy people (Israel) and upon the holy city (Jerusalem) to finish transgression and to make an end of sins.......
The 70th week has not been finished because there is no end of sins in Israel yet.
Does what Gabriel said mean transgression still prevails among unbelieving present Israel before the 70 week is finished ?
Until Lord Jesus returns to Armageddon battle to take back Israel and the world and then begin His Millennium, transgression still prevalent among the Jews and in Jerusalem. Isnt that what Gabriel meant ?
One of the worst end times transgression in Israel is the plan to rebuild the temple in Jerusalem as written in Revelation 11, which will be for antichrist and false prophet operation.
