Acts 22:22,23

Until he said this. As the Jews were crushed by foreign powers and occupation troops, they took comfort in the thought that when the Messiah came, the Gentile would be struck down and the Jew would stand with his foot on their neck. At this time the fires smoldered that would break out in the Jewish wars, terminating in the destruction of Jerusalem itself in 70 A.D. See Matthew 24 and notes. When Paul claimed their God had sent him to the Gentiles they explode in frenzied rage!!! They strip off their clothes and wave them in the air, throwing dust up in the air also, as a symbol of their rage!!!
