[5-8]: There seems to be a curious reversal here of Christ’s promise in John IV.13-14: ei omnis qui bibit ex aqua hac sitiet iterum qui autem biberit ex aqua quam ego dabo ei non sitiet in aeternum sed aqua quam dabo ei fiet in eo fons aquae salientis in vitam aeternam ‘Whosoever drinketh of this water, shall thirst again; but he that shall drink of the water that I will give him, shall not thirst for ever: But the water that I will give him, shall become in him a fountain of water, springing up into life everlasting’.
