Augustine of Hippo
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.
(Tr. xv. c. 20) Understand, that the woman had not a lawful husband, but had formed an irregular connexion with some one. He tells her, Thou hast had fire husbands, in order to shew her His miraculous knowledge.
