'Living Water' in the Bible

Jesus answered her, "If you [only] knew the [real] gift of God, and who it is that said to you, '[Please], give me a drink,' you would have asked Him, and He would have given you living water."

The woman [then] said to Him, "Sir, you do not have anything to draw [water] with, and the well is deep. Where will you get that living water?

For the Lamb, who is at the center of the throne, will be their Shepherd and will lead them to springs of living water. And God will wipe away every tear from their eyes."
