'Living Water' in the Bible

Jesus answered her, “If you knew [about] God’s gift [of eternal life], and who it is who says, ‘Give Me a drink,’ you would have asked Him [instead], and He would have given you living water (eternal life).”

She said to Him, “Sir, You have nothing to draw with [no bucket and rope] and the well is deep. Where then do You get that living water?

He who believes in Me [who adheres to, trusts in, and relies on Me], as the Scripture has said, ‘From his innermost being will flow continually rivers of living water.’”
