John 4:10

John 4:10. Jesus answered and said unto her, If thou knewest the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water.

Something better than the water from Jacob’s well. Though thou hast denied him a simple draught of water, he would not have denied thee something infinitely better, namely, living water. She little knew what that living water was.
