when jewish and christian scholars begin to take this war seriously , when they begin to really study what happened during the terrible years of the siege of jerusalem , the destruction of the temple , and the revolts that continued in palestine right up through bar kokhba , when they focus upon the persecution of christians in palestine by jews ; upon the civil war in rome in the 60s which kenneth l. gentry so well describes in his work before jerusalem fell ; as well as the persecution of jews in the diaspora during this period - in sum , when all of this dark era is brought into the light of examination - bible studies will change .
