'Water of Life' in the Bible

And he said to me, It has been. I am the Alpha and the Omega, the beginning and the end. I will give to him thirsting of the fountain of the water of life gratuitously.

And he showed me the pure river of the water of life, shining as crystal, going out of the throne of God and of the Lamb.

And the Spirit and the bride say, Come. And let him hearing say, Come. And let him thirsting come. And let him wishing, take the water of life freely.
