Revelation 21:6

Revelations 21:6 is a passage in the New Testament of the Christian Bible, appearing in the Book of Revelation. Fallout 3 uses the King James Version wording.

It is mentioned several times during the course of Fallout 3 by James, the Lone Wanderer's father, and is said to have been the his wife's favorite passage.

In the Book of Revelation, it is John's recollection of God's message to him. It implies, among other portents, that as God created the earth, so too shall he end it ("giveth and taketh away"). The passage also evokes many of the traditional associations with water: purity, life, and essence.

The Greek letters alpha and omega are essentially the same as the Latin letters A and Z, implying that God is the sum of all things. They are also a recurring motif in Christian imagery and iconography.

As applied to the post-apocalyptic setting of Fallout, the introduction of 21:6 in the first tutorial quest can be seen as a foreshadowing of Project Purity, an attempt to purify all the irradiated water in the Capital Wasteland simultaneously. After being reunited with James, the player learns that this passage was the inspiration for the project. In the game's climax, the code "216" is used to activate the water purifier.
