Trees bearing fruit, with seed in them, after their kind. (Gen. 1:10-12)
The Principle of the First-Use.
The first time that the Holy Spirit uses a word, it establishes the root-meaning of that word. All future uses of that word are branches that have to maintain their connection to the root, or you cannot have healthy fruit.
We Start Where God Starts
"Blessed is the man . . .
that meditates on My-Teaching day and night . . .
he shall be like a tree planted by streams of water,
which yields its fruit in season . . ." (Ps 1:3)
"Each tree is known by its fruit."
