John Gill 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)

When Jesus heard these things
Which the friends of the centurion related from him, and in his name; or which he himself delivered, coming up to Christ after them:

he marvelled at him ;
at his great humility and modesty, and the strength of his faith, and his manner of reasoning:

and turned him about ;
from him, and his friends:

and said unto the people that followed him ;
from the mount to Capernaum, and as he was passing along the streets:

I say unto you, I have not found so great faith, no, not in Israel ;
or "among the Israelites", as the Syriac; or "among the children of Israel", as the Persic; or "in all Israel", as the Arabic version reads, as he did in this single Gentile; (See Gill on Matthew 8:10).
