'Water of Life' in the Bible

And He said to me, It is done. I am the Alpha and Omega, the Beginning and the End. To him who thirsts I will give of the fountain of the Water of Life freely.

And he showed me a pure river of Water of Life, clear as crystal, proceeding out of the throne of God and of the Lamb.

And the Spirit and the bride say, Come! And let the one hearing say, Come! And let the one who is thirsty come. And he willing, let him take of the Water of Life freely.
