That should read, “the end of the Age”, which did occur in 70 AD. The OT always expressed the view that the Messiah would usher in the end of the age. But Jesus also ushered in the beginning of the new age, the age of redemption and full restitution with our Creator. This was not possible in the old age without complete fulfillment of the Law, which was impossible except by Jesus. And once fulfilled (completed), the book was closed and the new age took effect in the judgement of and complete destruction of Israel.
Yep.
Where I find myself challenged nowadays is when people read revelation, Daniel and all the other prophesy in the bible and are “positive” that it means such and such when, in fact, nobody ever knows what it means until AFTER it happens - unless they were given divine revelation.
