John heard in the prison (o de Iwanh akousa en twi desmwthriwi). Probably ( Luke 7:18 ) the raising of the son of the widow of Nain. The word for prison here is the place where one was kept bound ( Acts 5:21Acts 5:23 ; Acts 16:26 ). See Matthew 4:12 . It was in Machaerus east of the Dead Sea which at this time belonged to the rule of Herod Antipas (Jos. Ant. XVIII. v.2). John's disciples had access to him. So he sent word by (dia, not duo as in Luke 7:19 ) them to Jesus.
