John Chrysostom
Catena Aurea · Johannesevangelium 4
Jesus answered and said unto her, Whosoever drinketh of this water shall thirst again: But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life. The woman saith unto him, Sir, give me this water, that I thirst not, neither come hither to draw. Jesus saith unto her, Go, call thy husband, and come hither. The woman answered and said, I have no husband. Jesus said unto her, Thou hast well said, I have no husband: For thou hast had five husbands; and he whom thou now hast is not thy husband: in that saidst thou truly.
(Hom. xxxii. 1) The excellence of this water, viz. that he that drinketh of it never thirsts, He explains in what follows, But the water that I shall give him shall be in him a well of water springing up into everlasting life. As a man who had a spring within him, would never feel thirst, so will not he who has this water which I shall give him.
