33 "Either make the tree good, and its fruit good; or make the tree bad, and its fruit bad; for the tree is known by its fruit. 34 You brood of vipers! How can you speak good things, when you are evil? For out of the abundance of the heart the mouth speaks. 35 The good person brings good things out of a good treasure, and the evil person brings evil things out of an evil treasure. 36 I tell you, on the day of judgment you will have to give an account for every careless word you utter; 37 for by your words you will be justified, and by your words you will be condemned."
38 Then some of the scribes and Pharisees said to him, "Teacher, we wish to see a sign from you." 39 But he answered them, "An evil and adulterous generation asks for a sign, but no sign will be given to it except the sign of the prophet Jonah. 40 For just as Jonah was three days and three nights in the belly of the sea monster, so for three days and three nights the Son of Man will be in the heart of the earth. 41 The people of Nineveh will rise up at the judgment with this generation and condemn it, because they repented at the proclamation of Jonah, and see, something greater than Jonah is here! 42 The queen of the South will rise up at the judgment with this generation and condemn it, because she came from the ends of the earth to listen to the wisdom of Solomon, and see, something greater than Solomon is here!
43 "When the unclean spirit has gone out of a person, it wanders through waterless regions looking for a resting place, but it finds none. 44 Then it says, "I will return to my house from which I came.' When it comes, it finds it empty, swept, and put in order. 45 Then it goes and brings along seven other spirits more evil than itself, and they enter and live there; and the last state of that person is worse than the first. So will it be also with this evil generation."

Commentary on Matthew 12:33-37
(Read Matthew 12:33-37)
Men's language discovers what country they are of, likewise what manner of spirit they are of. The heart is the fountain, words are the streams. A troubled fountain, and a corrupt spring, must send forth muddy and unpleasant streams. Nothing but the salt of grace, cast into the spring, will heal the waters, season the speech, and purify the corrupt communication. An evil man has an evil treasure in his heart, and out of it brings forth evil things. Lusts and corruptions, dwelling and reigning in the heart, are an evil treasure, out of which the sinner brings forth bad words and actions, to dishonour God, and hurt others. Let us keep constant watch over ourselves, that we may speak words agreeable to the Christian character.
Commentary on Matthew 12:38-45
(Read Matthew 12:38-45)
Though Christ is always ready to hear and answer holy desires and prayers, yet those who ask amiss, ask and have not. Signs were granted to those who desired them to confirm their faith, as Abraham and Gideon; but denied to those who demanded them to excuse their unbelief. The resurrection of Christ from the dead by his own power, called here the sign of the prophet Jonah, was the great proof of Christ's being the Messiah. As Jonah was three days and three nights in the whale, and then came out again alive, thus Christ would be so long in the grave, and then rise again. The Ninevites would shame the Jews for not repenting; the queen of Sheba, for not believing in Christ. And we have no such cares to hinder us, we come not to Christ upon such uncertainties. This parable represents the case of the Jewish church and nation. It is also applicable to all those who hear the word of God, and are in part reformed, but not truly converted. The unclean spirit leaves for a time, but when he returns, he finds Christ is not there to shut him out; the heart is swept by outward reformation, but garnished by preparation to comply with evil suggestions, and the man becomes a more decided enemy of the truth. Every heart is the residence of unclean spirits, except those which are temples of the Holy Ghost, by faith in Christ.
