Before this time, Herod had arrested John. He had him chained and put in prison. He arrested John because of Herodias, the wife of Philip, Herod’s brother.
Herod himself had ordered his soldiers to arrest John and put him in prison. Herod did this to please his wife Herodias. She had been married to Herod’s brother Philip, but then Herod married her.
This was the first of all the miraculous signs Jesus did. He did it in the town of Cana in Galilee. By this he showed his divine greatness, and his followers believed in him.
