Matthew 12:34-36

King James Version

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.
