It is taken from Revelation 22 verse 17, however the Tenach is the foundation.

Gen 26:19 A springing well with healthy, fresh and drinkable water.
Lev 14:6, 50, 51, 15:13, Num 19:17 Here is spoken about cleansing.
Psalm 42:1 Thirsting for God.
Isaiah 55:1 (And for righteousness)

What can we say about living water? Living water flows like a stream; it is running. It is healthy, fresh and drinkable, it's useable and it cleanses. Whenever this is not the case it is dead water, it stands still and smells and is not drinkable. It is not useable and does not cleanse
And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely. KJV
