Augustine of Hippo

(Tr. xv. c. 16) Which is true indeed both of material water, and of that of which it is the type. For the water in the well is the pleasure of the world, that abode of darkness. Men draw it with the waterpot of their lusts; pleasure is not relished, except it be preceded by lust. And when a man has enjoyed this pleasure, i. e. drunk of the water, he thirsts again; but if he have received water from Me, he shall never thirst. For how shall they thirst, who are drunken with the abundance of the house of God? (Ps. 36:8.) But He promised this fulness of the Holy Spirit.
