Thematic Bible: Tree and its fruit

For that is not a good tree which produceth bad fruit, nor is the tree bad, which produceth good fruit: for every tree is known by it's fruit; for men do not gather figs from thorns, nor grapes from a bramble. A good man, out of the good treasure of his heart, bringeth forth that which is good; and an evil man, out of the evil treasure of his heart, bringeth forth that which is evil: for out of the abundance of the heart his mouth speaketh.
