Thematic Bible: Tree and its fruit

'For there is not a good tree making bad fruit, nor a bad tree making good fruit; for each tree from its own fruit is known, for not from thorns do they gather figs, nor from a bramble do they crop a grape. The good man out of the good treasure of his heart doth bring forth that which is good; and the evil man out of the evil treasure of his heart doth bring forth that which is evil; for out of the abounding of the heart doth his mouth speak.
