Luke 7:20

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:

hath sent us unto thee, saying, art thou he that should come, or look
we for another?
(See Gill on Matthew 11:3).
