John 4:46-49

46He came therefore again to Cana of Galilee, where he made the water wine. And there was a certain courtier in Capernaum whose son was sick.

47He, having heard that Jesus had come out of Judaea into Galilee, went to him and asked [him] that he would come down and heal his son, for he was about to die.

48Jesus therefore said to him, Unless ye see signs and wonders ye will not believe.

49The courtier says to him, Sir, come down ere my child die.
