John 4:48
King James Version
“Then said Jesus unto him, Except ye see signs and wonders, ye will not believe.”
Context
45Then when he was come into Galilee, the Galilaeans received him, having seen all the things that he did at Jerusalem at the feast: for they also went unto the feast.
46So Jesus came again into Cana of Galilee, where he made the water wine. And there was a certain nobleman, whose son was sick at Capernaum.
47When he heard that Jesus was come out of Judaea into Galilee, he went unto him, and besought him that he would come down, and heal his son: for he was at the point of death.
48Then said Jesus unto him, Except ye see signs and wonders, ye will not believe.
49The nobleman saith unto him, Sir, come down ere my child die.
50Jesus saith unto him, Go thy way; thy son liveth. And the man believed the word that Jesus had spoken unto him, and he went his way.
51And as he was now going down, his servants met him, and told saying, Thy son liveth.
