John Chrysostom — as excerpted in the Catena Aurea on John 4:46-54

“(Hom. xxxv. 3) They met him, to announce what had happened, and prevent Christ from coming, as He was no longer wanted. That the nobleman did not fully believe, is shewn by what follows: Then enquired he of them at what hour he began to amend. He wished to find out whether the recovery was accidental, or owing to our Lord’s word. And they said unto him, Yesterday at the seventh hour the fever left him. How obvious is the miracle? His recovery did not take place in an ordinary way, but all at once; in order that it might be seen to be Christ’s doing, and not the result of nature: So the father knew that it was at the same hour, in the which Jesus said unto him, Thy son livelh; and himself believed, and his whole house.”
