A.T. Robertson Commentary Luke 7:9

"And when Jesus heard these things, he marvelled at him, and turned and said unto the multitude that followed him, I say unto you, I have not found so great faith, no, not in Israel." — Luke 7:9 (ASV)

Turned (στραφεις). Second aorist passive participle of στρεφω, to turn. Common verb. A vivid touch not in Matthew's account. In both Matthew and Luke Jesus marvels at the great faith of this Roman centurion beyond that among the Jews. As a military man he had learned how to receive orders and to execute them and hence to expect obedience to his commands, He recognized Jesus as Master over disease with power to compel obedience.
