In context
Before · Matthew 12:34–35
34You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks. 35The good man out of his good treasure brings out good things, and the evil man out of his evil treasure brings out evil things.
36I tell you that every idle word that men speak, they will give account of it in the day of judgment.
