23:27 "Woe to you, teachers of the Law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of dead men's bones and everything unclean.
23:36 I tell you the truth, all this will come upon this generation.

He was not scolding the Pharisees at that time, but rather indicating that there would be such people in the future.

When God comes again, judgment will begin with the house of God.

Who will be judged first? It’s these people.

"The house of God" means the church.

From the time Christianity became the state Religion (around 325 AD) to the Middle Ages, and from the Middle Ages to Martin Luther’s Reformation, then from the Reformation to nowadays, there have been such "teachers" and "Pharisees" in every era.

Each generation will bear all the consequences of what they have done and be judged.

Who are the "teachers" and "Pharisees" now? When will the consequences manifest?

As believers, this is something for us to think about. We won't discuss it here.

True believers know it in their hearts, as we are living in this era.
