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.
Context
34 You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks.
35 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.
36 I tell you that every idle word that men speak, they will give account of it in the day of judgment.
