Matthew 12:34-36

34 [24] [AS] You brood of vipers, how can you say good things when you are evil? For from the fullness of the heart the mouth speaks.

35 A good person brings forth good out of a store of goodness, but an evil person brings forth evil out of a store of evil.

36 [25] [AT] I tell you, on the day of judgment people will render an account for every careless word they speak.
