Matthew 12:32-34

American Standard Version

³² And whosoever shall speak a word against the Son of man, it shall be forgiven him; but whosoever shall speak against the Holy Spirit, it shall not be forgiven him, neither in this ^[a]world, nor in that which is to come. ³³ Either make the tree good, and its fruit good; or make the tree corrupt, and its fruit corrupt: for the tree is known by its fruit. ³⁴ Ye offspring of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.
