Between the 11th and 12th verses there is a great break, and it is well to remember what passed in the interval: (1) the return to the Baptist, and the call of the six disciples (John 1:29-51); (2) the marriage at Cana, and the visit to Capernaum (John 2:1-12); (3) the cleansing of the Temple; the interview with Nicodemus, and the last testimony of the Baptist (John 2:13 to John 3:36). At this stage comes in the imprisonment of John (mentioned here, but not narrated till 14:3-5) and the consequent journey through Samaria to Galilee (John 4:1-42). The verse now before us may be noted as implying a ministry in Judæa, which for some reason the writer does not narrate.
