John 4:11-12

John 4:11-12. The woman saith unto him, Sir, thou hast nothing to draw with, and the well is deep: from whence then hast thou that living water? Art thou greater than our father Jacob, which gave us the well, and drank thereof himself, and his children, and his cattle?

That last word, "cattle", lets us see wherein the water of Jacob’s well could never be compared to the living water that Jesus gives. If beasts can partake of it, it is not that high and spiritual thing which immortal souls need, which Jesus came to give. Unwittingly, the woman had answered her own question, "Art thou greater than our father Jacob?"
