Matthew 12:29-39

29 "Or again, how can someone break into a strong man's house and make off with his possessions unless he first ties up the strong man? After that he can ransack his house.
30 "Those who are not with me are against me, and those who do not gather with me are scattering.
31 Because of this, I tell you that people will be forgiven any sin and blasphemy, but blaspheming the Ruach HaKodesh will not be forgiven.
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.
35 The good person brings forth good things from his store of good, and the evil person brings forth evil things from his store of evil.
36 Moreover, I tell you this: on the Day of Judgment people will have to give account for every careless word they have spoken;
37 for by your own words you will be acquitted, and by your own words you will be condemned."
38 At this some of the Torah-teachers said, "Rabbi, we want to see a miraculous sign from you."
39 He replied, "A wicked and adulterous generation asks for a sign? No! None will be given to it but the sign of the prophet Yonah.
