Face the troubles with faith and brave

Acts 21:27-40
When the seven days were nearly over, some Jews from the province of Asia saw Paul at the temple. They stirred up the whole crowd and seized him.
The commander came up and arrested him and ordered him to be bound with two chains. Then he asked who he was and what he had done.
The crowd that followed kept shouting, “Get rid of him!”
After receiving the commander’s permission, Paul stood on the steps and motioned to the crowd. When they were all silent, he said to them in Aramaic- Possibly Hebrew. Permitted speak for his defence.
Why?
Crowd are always blind to be stirred up.
Paul was very clear that what he is doing and what should do with wisdom and do not fear these. He has faith to face the future and troubles.
Paul can speak many languages.
How?
Paul has the faith and brave to face the trouble without fear.
