Mattityahu 12:33-42

Either make the etz (tree) tov (good) and its pri (fruit) will be tov, or make the etz nishchat (corrupt) and its pri will be rah; for by its pri the etz is known. You banim of nechashim (sons of snakes), how are you able to speak tovot (good things), for out of the abundance of the lev (heart) the mouth speaks. The ish tov (good man) out of the good otzar (treasure) brings forth good; and the ish rah out of the evil otzar brings forth evil. But I say to you, that for every careless lashon horah (evil speech) that men speak, they will be called to account on the Yom HaDin (the Day of Judgment). For by your devarim you will be pronounced tzodek (righteous), and by your devarim you will be charged with guilt. Then some of the Sofrim and Perushim answered Rebbe, Melech HaMoshiach, saying, Rabbi, we desire to see an ot (miraculous sign) from you. But Rebbe, Melech HaMoshiach answered them, Dor rah umnaef (an evil and adulterous generation) seeks for an ot (miraculous sign), but no ot will be given it except the ot of Yonah HaNavi. For just as Yonah was in the belly of the great fish SHLOSHAH YAMIM USHLOSHAH LAILAH (three days and three nights), so will be the Bar Enosh (Moshiach) in the heart of the earth SHLOSHAH YAMIM USHLOSHAH LAILOT (three days and three nights). The men of Nineveh will stand up at the Yom HaDin with this generation and they will condemn it, for the men of Nineveh made teshuva at the darshenen (preaching) of Yonah, and, hinei, something much greater than Yonah is here. The Queen of the South will be made to stand up alive at the Yom HaDin with this generation and will condemn it, for she came from the ends of the earth to listen to the chochmah of Sh'lomo and, hinei, something much greater than Sh'lomo is here.
