Close, off by 40 years. Rev 19 starts telling us that the harlot (Jerusalem) has been judged. Jerusalem is seen on fire with her smoke rising up "forever." We see that the Lamb has already had His revenge on the city which killed Him and many of the prophets.
Then the marriage supper comes implying the marriage had just taken place, probably on the same day that Rome lit the temple and city on fire.
There are two women mentioned in Revelation. The woman in Rev.12 is referring to Israel. The woman of Rev.17 - 18 is Mystery, Babylon the great, that city that sits on seven hills. These are two separate women. Jerusalem is not even mentioned in Rev.19. The city that is seen on fire and her smoke rising up forever and ever, is the woman who rides the beast and is not referring to Jerusalem and Israel.
According to Rev.12:6,14, the woman/Israel is cared for out in the desert in that place prepared for her by God for 1260 days, which is that last 3 1/2 years of that seven year period. It is that city that sits on seven hills that is destroyed, not Jerusalem.
