John 6:25

‘And when they found him at the other side of the sea, they said to him ‘Rabbi, when did you come here?'

The people were puzzled, but not aware of what had happened. They knew that no boat had been available and yet here Jesus was. They could think of no explanation. John, however, wishes it to be clear to his readers exactly what the position was.

‘They found him on the other side of the sea.' Possibly before they actually reached Capernaum which was their final destination. However they may have found him in Capernaum itself. This re-emphasis of ‘the other side of the sea' (compare v. 22) stresses the unusual nature of His arrival there, as does their question as to how He had come there.
