Luke 6:43 - 6:45
43 For there is no good tree which produces bad fruit, nor, on the other hand, a bad tree which produces good fruit. 44 For each tree is known by its own fruit. For men do not gather figs from thorns, nor do they pick grapes from a bramble bush. 45 The good man out of the good treasure of his heart brings forth what is good; and the evil man out of the evil treasure brings forth what is evil. For his mouth speaks from the abundance of his heart.
