'Living Water' in the Bible

Jesus answered and said unto her, If thou knewest the gift of God, and who it is that saith unto thee, Give me to drink; thou wouldst have asked of Him, and He would have given thee living water.

The woman saith unto Him, Sir, thou hast nothing to draw with, and the well is deep: whence then hast thou the living water?

He that believeth on me, as the scripture hath said, rivers of living water shall flow from within him.

For the Lamb, that is in the midst of the throne, shall feed them, and shall lead them to fountains of living waters: and God will wipe off every tear from their eyes.
