Luke 7:18 - Joseph Benson’s Commentary on the Old and New Testaments

And the disciples of John showed him these things All this while John the Baptist was in prison; Herod having confined him for the freedom which he took in reproving his adulterous commerce with Herodias, his brother Philip's wife. But his confinement was not of the closest kind, for his disciples had access to him frequently. In one of those visits they gave him an account of the election of the twelve apostles to preach the gospel, and of Christ's miracles, particularly that he had lately raised from the dead Jairus's daughter and the widow of Nain's son; as is plain from what Luke says in the following verses, who brings in the history of John's message immediately after these miracles.
