John 4:14

14. Shall never thirst Will never thirst; the simple future.

In him a well The supply will not be, like the material water from an external and distant spring, but within. And while the well is there the ever-living water will incessantly spring up. The water can never die or dry; but the well may, by sin and apostacy, be removed. See notes on John 5:24; John 6:40. By eating of the Tree of Life our first parents were made deathless, and so God, separated it from them for sin, and they became mortal.

Springing up Like a fountain jetting upwards.

Into everlasting life It is a water of spiritual life, but it jets up into an immortal life; the water of spiritual life, as it ascends, crystallizes into an eternal life.
