Matthew 12:34-36

Amplified Bible

³⁴ You brood of vipers, how can you speak good things when you are evil? For the mouth speaks out of that which fills the heart. ³⁵ The good man, from his [inner] good treasure, brings out good things; and the evil man, from his [inner] evil treasure, brings out evil things. ³⁶ But I tell you, on the day of judgment people will have to give an accounting for every careless or useless word they speak.
