In this chapter the glory of the Lord literally leaves the temple. The big throne thing from chapter one collects it.
It is like a cloud, it goes from the holy of holies to the threshold and then it departs altogether.
The Messenger who marked the faithful people to skip destruction in the last chapter takes coals from the big throne-with-wheels thing and spreads them about the city.
This predicts the burning of the city, which did in fact happen a few years later. The bitter pill the Israelites have to swallow is that the judgement may be executed by invaders but it comes comes from God.
