Albert Barnes Commentary John 4:46

"He came therefore again unto Cana of Galilee, where he made the water wine. And there was a certain nobleman, whose son was sick at Capernaum." — John 4:46 (ASV)

A certain nobleman. One who was of the royal family, connected by birth with Herod Antipas; or one of the officers of the court, whether by birth allied to him or not. It seems that his ordinary residence was at Capernaum. Capernaum was about a day's journey from Cana, where Jesus then was.
