John 4:51 - Ellicott's Commentary On The Whole Bible

And as he was now going. — Many a long mile lay between him and his child, and many an anxious thought must have come to his mind as he journeyed homeward. Now faith would be strong, and now almost give way; but he travels on with the words, “Thy son liveth,” which had come to him as a voice from heaven, sustaining and cheering him. Again he hears the same words, “Thy son liveth!” but they are spoken by the servants, who have come to meet him, and bring from Capernaum the glad news that he had himself heard at Cana.
