³⁴ You brood of vipers,^(A) how can you who are evil say anything good? For the mouth speaks^(B) what the heart is full of.

¹⁸ But the things that come out of a person’s mouth come from the heart,^(A) and these defile them.

¹⁹ For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander.^(A)

²¹ For it is from within, out of a person’s heart, that evil thoughts come—sexual immorality, theft, murder,

⁴⁵ A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.^(A)
