Context / meaning
Matthew 12 [30.] “He who is not with me is against me, and he who doesn’t gather with me, scatters. Therefore I tell you, every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven men. Whoever speaks a word against the Son of Man, it will be forgiven him; but whoever speaks against the Holy Spirit, it will not be forgiven him, neither in this age, nor in that which is to come.
Matthew 12 [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. You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks. The good man out of his good treasure brings out good things, and the evil man out of his evil treasure[d] brings out evil things. I tell you that every idle word that men speak, they will give account of it in the day of judgment. For by your words you will be justified, and by your words you will be condemned.”
Matthew 12 [38.] Then certain of the scribes and Pharisees answered, “Teacher, we want to see a sign from you.”
Matthew 12 [39.] But he answered them, “An evil and adulterous generation seeks after a sign, but no sign will be given it but the sign of Jonah the prophet. For as Jonah was three days and three nights in the belly of the whale, so will the Son of Man be three days and three nights in the heart of the earth. The men of Nineveh will stand up in the judgment with this generation, and will condemn it, for they repented at the preaching of Jonah; and behold, someone greater than Jonah is here. The queen of the south will rise up in the judgment with this generation, and will condemn it, for she came from the ends of the earth to hear the wisdom of Solomon; and behold, someone greater than Solomon is here.
d. Matthew 12:35 TR adds “of the heart”.
