John 2:8
Then he told them, 'Now draw some out and take it to the master of the banquet.' They did so, and the master of the banquet tasted the water that had been turned into wine — the transformation occurs invisibly during the drawing process. No formula, prayer, or gesture precedes the miracle; Jesus' word effects change. The master of the banquet's unawareness that the wine is miraculous emphasizes the sign's hiddenness, known only to servants and disciples.
