Matthew 12:33-35

Twentieth_Century(i) 33 You must assume either that both tree and fruit are good, or that both tree and fruit are worthless; since it is by it's fruits that a tree is known. 34 You brood of vipers! how can you, evil as you are, say anything good? For what fills the heart will rise to the lips. 35 A good man, from his good stores, produces good things; while an evil man, from his evil stores, produces evil things.
