Matthew 12:32-34

Complete Jewish Bible

³² One can say something against the Son of Man and be forgiven; but whoever keeps on speaking against the Ruach HaKodesh will never be forgiven, neither in the ‘olam hazeh nor in the ‘olam haba.

³³ “If you make a tree good, its fruit will be good; and if you make a tree bad, its fruit will be bad; for a tree is known by its fruit. ³⁴ You snakes! How can you who are evil say anything good? For the mouth speaks what overflows from the heart.
