Luke 6:43-45 Certainly a good tree does not produce bad fruit: nor does a bad tree produce good fruit.

Mace⁽ⁱ⁾ ⁴³ Certainly a good tree does not produce bad fruit: nor does a bad tree produce good fruit. ⁴⁴ for every tree is known by its fruit: it is not on thorns that men gather figs, nor do they gather grapes on a bramble bush. ⁴⁵ a good man out of the good treasure of his heart produces what is good: and an evil man out of the evil treasure of his heart produces what is evil: for 'tis from the abundance of the heart, that the mouth speaketh.
