'Fountain' in the Bible

And immediately her fountain of blood was dried up, and she knew in her body that she was cured from the scourge.

Now a fountain of Jacob's was there; Jesus therefore, being wearied with the way he had come, sat just as he was at the fountain. It was about the sixth hour.

but whosoever drinks of the water which I shall give him shall never thirst for ever, but the water which I shall give him shall become in him a fountain of water, springing up into eternal life.

Does the fountain, out of the same opening, pour forth sweet and bitter?

And he said to me, It is done. I am the Alpha and the Omega, the beginning and the end. I will give to him that thirsts of the fountain of the water of life freely.
