'Water of Life' in the Bible

He also said: "It has now come to pass. I am the Alpha and the Omega, The Beginning and the End. To him who thirsts I will freely give Of the spring of the Water of life.

And he showed me the river of the Water of Life, clear as crystal, Flowing out from the throne of God, and of the Lamb,

"And the Spirit and the Bride say 'Come!' And let him who hears, say 'Come!' And let him who thirsts, come; And whoever wills, let him take the Water of Life freely."
