When he heard that Jesus came out of Judea 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.
All Commentaries on John 4:47 Go To John 4
Cyril of Alexandria
AD 444
The nobleman cometh as to One able to heal, but he understandeth not yet that He is by Nature God: he calleth Him Lord, but giveth not at all the true dignity of Lordship. For he would have straightway fallen down and besought Him, not that he should by all means come to his house, and go down with him to the sick lad; but should rather with authority and God-befitting command drive away the sickness that fell on him. For what need for Him to be present to the sick, whom He could easily heal, even absent? how was it not utterly without understanding to suppose that He is superior to death, and in no wise to hold Him God Who is filled with God-befitting Power?
