John 4:46-49

Once more he visited Cana in Galilee, where he had turned the water into wine. And there was a certain royal official whose son lay sick at Capernaum. When this man heard that Jesus had arrived in Galilee from Judea, he went to him and begged him to come and heal his son, who was close to death. “Unless you people see signs and wonders,” Jesus told him, “you will never believe.” The royal official said, “Sir, come down before my child dies.”
