John Gill Commentary Luke 7:20

"And when the men were come unto him, they said, John the Baptist hath sent us unto thee, saying, Art thou he that cometh, or look we for another?" — Luke 7:20 (ASV)

When the men were come to him
To Jesus; "those two men", as the Arabic version reads; "the disciples", as the Persic version; the same that John sent from the castle of Machaerus, where he was now a prisoner, to Christ, who was teaching in some city or town of Galilee:

they said, John the Baptist ;
so well known by his being the administrator of the ordinance of baptism:

has sent us to you, saying, are you he that should come, or are we to look
for another?
(See Gill on Matthew 11:3).
