Charles Ellicott Commentary Luke 17:11

"And it came to pass, as they were on their way to Jerusalem, that he was passing along the borders of Samaria and Galilee." — Luke 17:11 (ASV)

And it came to pass, as he went to Jerusalem.—This is the first distinct note of time in St. Luke’s narrative since Luke 9:51. It appears to coincide with the journey described in Matthew 19:1 and Mark 10:1, and it is the commencement of the last progress through the regions where our Lord had already carried on His ministry.

The fact that this journey led Him through Samaria (apparently through that part of it which lay on the borders of Galilee) is peculiar to St. Luke and is obviously reported in connection with the miracle that follows. The other Gospels, by contrast, dwell on the departure from Galilee and the continuation of the journey to Jerusalem by the route east of the Jordan valley.
