John 4:9-10

The Samaritan woman therefore saith unto him, How is it that thou, being a Jew, askest drink of me, who am a Samaritan woman? (For Jews have no dealings with Samaritans.) 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.
