People were amazed as a result of Jesus expelling a demon from a man.

Mark 1:21-28

21 Later Jesus and those disciples arrived at Capernaum town. On the next ◄Sabbath/Jewish rest day►, after Jesus had entered ◄the synagogue/the Jewish meeting place►, he began teaching the people who had gathered there. 22 They were continually amazed at the way he taught. He did not just teach what others had taught, like the men who teach the Jewish laws did. They habitually just repeated what other people had taught. Instead, he taught with his own authority. 23 Suddenly, while he was teaching, a man appeared in their worship place who had an evil spirit in him, and he shouted, 24 “Jesus, from Nazareth town, since we evil spirits have nothing in common with you, ◄do not interfere with us!/what do you want with us evil spirits?► [RHQ] ◄Do not destroy us now!/Have you come to destroy us now?► [RHQ] I know who you are. I know that you are the holy one who has come from God!” 25 Jesus rebuked the evil spirit, saying, “Be quiet! And come out of the man!” 26 The evil spirit shook the man hard. He screamed loudly, and then he came out of the man and left. 27 All the people who were there were amazed. As a result, they discussed this among themselves, exclaiming, “◄This is amazing!/What is this?► [RHQ] Not only does he teach in a new and authoritative way, but also the evil spirits obey him when he commands them!” 28 The people very soon told many others throughout the whole Galilee district what Jesus had done.
