Matthew 8:7 - Ellicott's Commentary On The Whole Bible

I will come and heal him. — In St. Luke’s report the words are omitted, but they are implied in our Lord’s act in going with the elders of the synagogue. While He went, some one, it would seem, ran on in front to tell the centurion that his prayer was heard. Then, in his humility, he sends off some of his friends with the message, which St. Matthew records as if it had come from his own lips.
