Origen

“ And we might make a like inquiry in regard to other things; but by-way of illustration the narrative about the woman of Samaria sufficeth, “Every one that drinketh of this water shall thirst again; but whosoever drinketh of the water that I shall give him shall never thirst.” [1] For there, also, so far as the mere form of expression is concerned, the Samaritan woman would seem to have thought that the Saviour was giving a promise about sensible water, when He said, “Whosoever drinketh of the water that I shall give him shall never thirst.” ”
