Psalm 1:3 He is like a tree planted by streams of water that yields its fruit in its season, and its leaf does not wither. In all that he does, he prospers.
Jeremiah 17:8 He is like a tree planted by water, that sends out its roots by the stream, and does not fear when heat comes, for its leaves remain green, and is not anxious in the year of drought, for it does not cease to bear fruit.”
The tree planted in the world will have seasons when it prospers but in the dry season it will wither.
The tree that plants roots in the water will draw from the hidden water when the river bed dries up.
John 7:38 Whoever believes in me, as the Scripture has said, “Out of his heart will flow rivers of living water.”
Living waters never dry up.
