Matthew 12:35 in the World English Bible
The good man out of his good treasure brings out good things, and the evil man out of his evil treasure brings out evil things.
Context
34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.
35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.
36 But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment.
