Herod was uncertain about who was doing these miracles.

Luke 9:7-11

7 Herod Antipas, the ruler of that district, heard about the things that Jesus and his disciples were doing. He had previously commanded his soldiers to execute John the Baptizer, so now he was perplexed, because some people were saying that John had become alive again and was doing those miracles. 8 Others were saying that the prophet Elijah had appeared again as had been prophesied. Others were saying that one of the other former prophets had become alive again and was doing those miracles. 9 But Herod said, “It cannot be John who is doing these things, because I commanded my soldiers to cut off his head. So who is this man that I am hearing these things about?” And he kept wanting to see Jesus.

10 When the apostles returned from traveling to various towns, they told Jesus the things that they had done. Then he took them and they went by themselves by boat to a town called Bethsaida. 11 But when the crowds of people who had been with Jesus found out about that, they followed him on land. When they got to where he was, he welcomed them. He taught them about how God is going to some day ◄rule as king/have complete control over people’s lives►. He also healed the sick people.
