Jesus replied to her, “If you only knew what God’s gift is and who is asking you for a drink, you would have asked him for a drink.  He would have given you living water.”
¹¹ The woman said to him, “Sir, you don’t have anything to use to get water, and the well is deep.  So where are you going to get this living water? ¹² You’re not more important than our ancestor Jacob, are you?  He gave us this well.  He and his sons and his animals drank water from it.”
¹³ Jesus answered her, “Everyone who drinks this water will become thirsty again. ¹⁴ But those who drink the water that I will give them will never become thirsty again.  In fact, the water I will give them will become in them a spring that gushes up to eternal life.”
