Forty years (a generation) into this dispensation in AD 70 the Romans slaughtered millions of Jews and dispersed them among the nations. There is another forty-year (a generation) prophecy at the end of this dispensation. Jesus spoke of the resurrection of Israel, as the Jews would become a nation again, in the parable of the fig tree. He says, “…Verily I say unto you, This generation shall not pass, til all these things be fulfilled.”
