John Gill Commentary Luke 9:57

"And as they went on the way, a certain man said unto him, I will follow thee whithersoever thou goest." — Luke 9:57 (ASV)

And it came to pass, as they went in the way
From one village of the Samaritans, to the other; though if this is the same history related in (Matthew 8:19) it was as Christ went from Capernaum to the sea side, in order to go to the other side of it; and must be inserted here, without regard to the order of time:

a certain man said unto him ;
if the same as in Matthew, he is there said to be a "Scribe";

Lord, I will follow you, wherever you go .
The Arabic and Ethiopic versions read these words by way of question, "Lord, shall I not follow you wherever you go?" (See Gill on Matthew 8:19).
