John Gill Commentary Luke 6:6

"And it came to pass on another sabbath, that he entered into the synagogue and taught: and there was a man there, and his right hand was withered." — Luke 6:6 (ASV)

And it came to pass also on another sabbath
Whether the following sabbath, or some time after, is not certain,

that he entered into the synagogue .
The Arabic version reads, "into their synagogue", as in (Matthew 12:9) the synagogue of the Jews; in what place, whether at Capernaum, or some other city of Galilee, is not so clear: and taught ;
explained the Scriptures to the people, and instructed them in the doctrines of the Gospel:

and there was a man whose right hand was withered ;
who was in the synagogue, and one of his hearers; (See Gill on Matthew 12:10)
