Matthew 24:6 - Jesus is telling His disciples they will hear rumors of wars but the end is not yet. And we know this because it all revolves around the destruction of Jerusalem 40 years after Jesus returned to Heaven.
Hebrews 8:13 - The old covenant is ready to vanish away. And become obsolete. Both Covenant's existed side by side from 30 AD to 70 AD. Notice vanish away was about to happen, which would be the Destruction of Jerusalem. These were not events thousands of years in the future. They were not world wide events, Jesus told His disciples they could avoid them by fleeing to the mountains.
Matthew 21:40-45 The Pharisees knew it was them. This is a prediction of Jesus and was in fulfillment by the Destruction of Jerusalem in AD 70, throughout the whole world.
